soft code a do loop control?

Hello all,

I would like to soft code a do loop or any loop for that matter with the 'key' I have built in a small proc sql data set.  I am not sure how or if this is possible help or other ideas please?

proc sql;
create table TERM_TBL_DIST as
select DISTINCT strm||'*'||acad_career as key, STRM, ACAD_CAREER
from &snapshotlib..PS_TERM_TBL
WHERE ACAD_YEAR BETWEEN "&year_four." and "&year.";
quit;
proc print data = TERM_TBL_DIST noobs n;run;

My data set has 103 obs at this time and will change over semesters. Here are samples of my key and two vars that build it.

                      ACAD_
                                   key          STRM    CAREER

                                   2153*UGRD    2153     UGRD
                                   2153*VETM    2153     VETM
                                   2155*MEDI    2155     MEDI
                                   2155*PHAR    2155     PHAR
                                   2155*UGRD    2155     UGRD
                                   2155*VETM    2155     VETM
                                   2157*BUSN    2157     BUSN
                                   2157*GRAD    2157     GRAD
                                   2157*IALC    2157     IALC
                                   2160*UGRD    2160     UGRD
                                   2163*BUSN    2163     BUSN
                                   2163*GRAD    2163     GRAD
                                   2163*IALC    2163     IALC
                                   2163*MEDI    2163     MEDI
                                   2165*BUSN    2165     BUSN
                                   2165*GRAD    2165     GRAD
                                   2165*IALC    2165     IALC


What I am asking is simply how do I "auto" or soft code the v= 1, 2,3,4, … below with my build key:

 

data A;
do v = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 13, 21;
/* my work here */
 output;
end;
run;

 

PS sorry if I have titled this wrong, I don't know what I don't know and all...  LOL

TIA  -KJ

Re: soft code a do loop control?

It is not at all clear what your question may be.

Are you wanting to do something for each value of your key? If so and Key is already in your data then

 

Data A;

   set TERM_TBL_DIST ; /*<= since you created this data set with Key in it*/

   <my work>

run;

will process each record in the TERM_TBL_DIST data set. Data step implies a "loop" through each record in the data set(s) on the SET statement.

 

If you need more help it will help to post a small example of the starting data you have and the desired result along with rules.

 

You might consider using the CATX function instead of the || operators. The || can result in embedded blanks depending on the values of the variables concatenated. Catx ('*',strm, acad_career) as Key

Re: soft code a do loop control?

Well I am not sure this will help but in my case I have a double nested do loop and the outer loop is hard coded to 1-5 for 5 acad_careers and it really should be soft coded to my key shown before... to build out a calendar of snapshot db dates and cross walk information for the terms/acad_careers for reporting purposes for example -9 weeks before term A. compared to -9 weeks before term B.  bla bla...  I was trying to save the list from a lot of details that are not important to the big picture...

 

 

Anyway here is a bit more verbose code do loop but still very stripped down from my final need.

 

data calendar;

format t_SNAP_DATE date9.;

/* this next line needs to become */

      do j = 1 to 5;

/* efectivly somthing like this  next line at least from a hard coded example I saw on a blog page */

do j = 2137*BUSN, 2137*GRAD, 2137*MEDI, 2137*PHAR, 2137*UGRD, 2137*VETM, 2140*UGRD, 2143*BUSN, 2143*GRAD, 2143*MEDI, 2143*PHAR, 2143*UGRD, 2143*VETM, 2145*BUSN, 2145*GRAD, 2145*MEDI, 2145*PHAR, 2145*UGRD, 2145*VETM, 2147*BUSN;

/* however I do not want it hard coded, like above I want to make it softcoded if posible ?????? 

I want the 'key' to be the control list and to be able to use the two fields &strm. + &acad_career. in the body of my do loop.  And as you can see I do not 'set' a data set in this code I am building it from scrach, my output needs to be keyed on  SNAP_DATE, STRM, and ACAD_CAREER    oops I think my proc sql needs to pass along start date too, however I can do that on my own... that is all I can add at this time,   Does that help???????? */

 

      do i = -386 to &term_day_ct.;

                  STRM=&STRM.;

                                           /*                                 1     2     3     4     5              */

                  ACAD_CAREER=j;   /* will be changed from number to GRAD, MEDI, PHAR, UGRD, VETM, etc later */
                  /* so the above becomes */
                  ACAD_CAREER=&ACAD_CAREER.;

                  /* etc */

                  term_begin_dt=put(Intnx( 'Day' , "&term_begin_d."d, 0 ),date9.);

                  SNAP_DATE=put(Intnx( 'Day' , "&term_begin_d."d, i ),date9.);

                  t_SNAP_DATE=(input(SNAP_DATE,date9.));

                  month=month(t_SNAP_DATE);

     

      output;

      end;

      drop i;

      end;

      drop j;

run ;

Re: soft code a do loop control?

Example input data and desired output will clarify a host of issues.

 

Here's a stab at some of what I think you may be attempting.

proc sql noprint;
   select distinct quote(acad_career)  into: al separated by ','
   from &snapshotlib..PS_TERM_TBL;
   select distinct  quote(strm) into: sl separated by ','
   from &snapshotlib..PS_TERM_TBL;
quit;
%put &al &sl;
data junk;
   do s = &sl;
   do a = &al;
   output;
      key = catx('*',s,a);
   end;
   end;
run;

Re: soft code a do loop control?

I'm also guessing at your intentions.  Here's one possibility:

 

proc sql noprint;

select "'" || strip(key) || "'" into : key_list separated by ' ' from _ACAD;

quit;

 

That gives you a macro variable holding a list of the keys:

 

'2153*UGRD' '2153*VETM' ....

 

Then you can use the ones you choose by setting up an array:

 

data A;

array keys {&sqlobs} $ 9 _temporary_ (&key_list);
do v = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 13, 21;

    particular_key = keys{v};
/* my work here */
 output;
end;
run;

Re: soft code a do loop control?

[ Edited ]

The "into" key word I have used, but am totally lost with the use of "arrays".   I think of arrays like an old Fortran programmer and don't get the use of them in SAS one bit...

ugggg!

 

I should have thought of the “into” option.   Sorry that could have shortened/simplifed my question.

PS the line:

do v = 1, 1, 2, 3, 5, 8, 13, 21;

was just a starting hard coded point, just the example of what I wanted to soft code for my control list, nothing more...

Re: soft code a do loop control?

SAS arrays (in simplest of all possible terms) contain some of the variables within a single row of data.  This example is not the simplest of all possible terms, because this array is temporary.  That means it contains a set of constants rather than set of variables.

 

The intent of the DO loop here is to execute the "my work here" section 12 times.  The first time, since v=1, PARTICULAR_KEY is "2153*UGRD" or the first element in the set of constant terms.  The second time, since v=2, PARTICULAR_KEY is "2153*VETM" or the second element in the set of constant terms.  The value of V lets PARTICULAR_KEY take on a matching value from a set of possible values.  I'm not sure if that was your intent here, but that's how the code functions.

 

Whether this makes sense to do at all might depend on "my work here" and what work needs to be performed.  It's entirely possible that the approach needs to change 100%, depending on what goes into "my work here".

Re: soft code a do loop control?

Astounding,

Thanks for your help so far... 

 

Well I get up to the line %put &sqlobs.;   /*see below */

and my result of that line is 103 what i expect.

 

so here is my code:

proc sql;
create table TERM_TBL_DIST as
select DISTINCT 
STRM,
ACAD_CAREER,
datepart(term_begin_dt) format date9. as term_begin_d
from &snapshotlib..PS_TERM_TBL
WHERE ACAD_YEAR BETWEEN "&year_four." and "&year.";
quit;
proc sql;
create table TERM_TBL_DIST1 as
select DISTINCT 
Catx ('*',strm,acad_career,put(term_begin_d,date9.)) as KEY,
STRM,
ACAD_CAREER,
term_begin_d
from TERM_TBL_DIST;
quit;
proc print data = TERM_TBL_DIST1 noobs n;run;
proc sql noprint;
select DISTINCT  "'" || strip(key) || "'" into : key_list separated by ', '
from TERM_TBL_DIST1;
quit;
%put &key_list.;
%put &sqlobs.;

..up to that point.  I still am not sure what I am doing wrong with the rest of this code:

data a;
array keys {&sqlobs} $ 9 _temporary_ (&key_list);
do v=&key_list;
/*= 1 to {&sqlobs};*/   /* <-- here I tried doing a fixed loop with the now known size that didn't work for me either */
	current_key=keys{v};
	put current_key;
	strm=scan(&current_key.,1,'*');    
	acad_career=scan(&current_key.,2,'*');
	term_begin_d=scan(&current_key.,3,'*');
		/*  do inner loop here??   this part of the code will create records 1 for
each day 386 some days before the start of each term through to the last
day of the term... My inner do loop works as I want it to at this time, thus not snown again
*/
END;
drop v; RUN; proc print data=a;run;

Re: soft code a do loop control?

Two items stand out.  If you have errors beyond that, it would be helpful to show the log.

 

First, it would be correct for the DO loop to go from 1 to 103.  You can use 1 to &sqlobs if you need flexibility for cases where 103 would not be the right number.

 

Second, there is no need to use macro language such as &CURRENT_KEY.  Just use CURRENT_KEY instead.  It's a character variable with the proper value.

 

That will get you further ... see if it's far enough.

Re: soft code a do loop control?

Getting very close, it does not seem to either like that last field connactinated or my date format.

 

proc sql;
create table TERM_TBL_DIST as
select DISTINCT
STRM,
ACAD_CAREER,
datepart(term_begin_dt) format date9. as term_begin_d
from &snapshotlib..PS_TERM_TBL
WHERE ACAD_YEAR BETWEEN "&year_four." and "&year.";
quit;
proc sql;
create table TERM_TBL_DIST1 as
select DISTINCT
/*Catx ('*',strm,acad_career,put(term_begin_d,date9.),'-') as KEY,*/
Catx ('*',strm,acad_career,term_begin_d,'-') as KEY,
STRM,
ACAD_CAREER,
term_begin_d
from TERM_TBL_DIST;
quit;
proc print data = TERM_TBL_DIST1 noobs n;run;
proc sql noprint;
select DISTINCT  "'" || strip(key) || "'" into : key_list separated by ', '
from TERM_TBL_DIST1;
quit;
%put &key_list.;
%put &sqlobs.;

data a;
array keys {&sqlobs} $ 9 _temporary_ (&key_list);
do v= 1 to &sqlobs.;
    current_key=keys{v};
    strm=scan(&current_key.,1,'*');
    acad_career=scan(&current_key.,2,'*');
    term_begin_d=scan(&current_key.,3,'*');
    junk=scan(&current_key.,4,'*');   /* looking to see if it disliked the trailing field, seems to drop it and the date  */

        /*    do inner loop here??*/
    output;
/*    drop v;*/
END;
RUN;
proc print data=a noobs n;run;

it is dropping the date field before i go int my inner loop.

output sample:


                             current_             acad_      term_
                       v        key       strm    career    begin_d    junk

                      101    2175*PHAR    2175     PHAR
                      102    2175*UGRD    2175     UGRD

@kjohnsonm

I believe what you're trying to do is not that hard as such BUT: It would really help if you could post some representative sample data (data steps creating such data) and describe the desired result as this would 1) remove the guess work for us and 2) allow us to post fully working and tested code.

Re: soft code a do loop control?

It looks like you considered another version when adding the date inside CATX.  put(term_begin_dt, date9.) might very well be correct but there's no way for me to tell.  You haven't shown what you are hoping to get as a result for that piece.

 

There are still references to &CURRENT_KEY, a macro variable that (at least as far as I can see) doesn't exist.  From what you have shown here, all instances of &CURRENT_KEY should remove the ampersand.

 

If arrays make you uncomfortable, take advantage of the fact that you have inserted commas between the items in &KEYLIST.  You could replace the three lines beginning with the ARRAY statment, and simply code:

 

do current_key = &keylist;

Re: soft code a do loop control?

Okay my latest version of this code with datalines.

What it seems to be doing is my key is dropping the date part, 'junk' was just a test to see if this code did not like to give the last item in a 'scan' command.

 

I expect to have a full "current_key with date" and term_begin_d and junk columns when done.

 

data TERM_TBL_DIST;
input	@01 STRM $4.
		@10 ACAD_CAREER $4.
		@19 term_begin_d date9.
		@33 junk $1.;
format	strm $4.
		acad_career $4.
		term_begin_d date9.
		junk $1.;

/*        ACAD_         term_
STRM    CAREER      begin_d    junk
*/

Re: soft code a do loop control?

While you have assigned a DATE9 format to your date variable, you did not use that format when forming your string:

 

compress("'" || put(term_begin_d,9.) || "'",,'s') as term_begin_d,

 

I think what you are looking for is this:

 

compress("'" || put(term_begin_d,date9.) || "'",,'s') as term_begin_d,

Re: soft code a do loop control?

I still don't understand what your desired end result should be.

 

Your latest code version transposes your source data set from a long to a wide structure (held in a macro variable) only to then being transposed back from wide to long for the result table. That appears to me to be pretty useless. See below code who gives you the same result than what you've done so far.

data have;
  input @01 STRM $4.
    @10 ACAD_CAREER $4.
    @19 term_begin_d date9.
    ;
  format  strm $4.
    acad_career $4.
    term_begin_d date9.
    ;
  datalines;
2127     BUSN     20AUG2012     -
2127     GRAD     20AUG2012     -
2127     MEDI     20AUG2012     -
2127     PHAR     20AUG2012     -
2127     UGRD     20AUG2012     -
2127     VETM     20AUG2012     -
2130     UGRD     01AUG2012     -
2133     BUSN     07JAN2013     -
2133     GRAD     07JAN2013     -
2133     MEDI     07JAN2013     -
2133     PHAR     07JAN2013     -
2133     UGRD     07JAN2013     -
2133     VETM     07JAN2013     -
;
run;

data want;
  length current_key $9;
  set have;
  current_key=catx('*',strm,acad_career);
run;

Based on the sample data you've provided, can you explain how your desired result table should look like. You have some ""inner loop" comment in your code. What should happen in this inner loop and would you then want to write an output row per iteration over the inner loop?
