Help with the following

sasuser1000 — Wed, 13 Apr 2011 15:27:57 GMT

Hi,

This is only part of the code but my main problem in the do loop, does someone knows what am I doing wrong?

%macro ADJUST;
data _null_;
set list1 nobs=nobs;
call symput('nobsI',compress(put(nobs,11.)));
stop;
run;

%do I=1 %TO SYMGETn('nobsI');
.etc
.etc
.etc
.

This is the LOG:

ERROR: Required operator not found in expression: SYMGETn('nobs')
ERROR: The %TO value of the %DO I loop is invalid.
ERROR: The macro ADJUST will stop executing.

Hello
SYMGET is a macro function used in the DATA STEP only. I would just resolve your macro variable NOBS1 by substituting SYMBETn('oobs1') with &nobs1 and thata should do the trick.

Hi Darrylovia!

Thanks so much for answering

but something went wrong when I did the changes, I think i didn't really understand what to change (I am kind of new in MACRO).

Here are the changes I have done:

%macro ADJUST;
data _null_;
set list1 nobs=nobs;
call symbetn('nobs1',compress(put(nobs,11.)));
stop;
run;

%do I=1 %TO &nobs1 ;/*change to total number of records in data6*/

LOG:

data _null_; set list1 nobs=nobs; call symbetn('nobs1',compress(put(nobs,11.))); stop
-------
251
1 ! ; run;

ERROR 251-185: The subroutine SYMBETN is unknown, or cannot be accessed. Check your spelling.
Either it was not found in the path(s) of executable images, or there was
incorrect or missing subroutine descriptor information.

Sorry I meant to reply with this

%macro ADJUST;
data _null_;
set list1 nobs=nobs;
call symput('nobsI',compress(put(nobs,11.)));
stop;
run;

%do I=1 %TO SYMBETn('nobsI');

I still get an error:

ERROR: Required operator not found in expression: SYMBETn('nobsI')
ERROR: The %TO value of the %DO I loop is invalid.
ERROR: The macro ADJUST will stop executing.

Hello SASUser100,

Please explain what value do you want to use as an upper limit in your %do loop?

%do I=1 %TO &nobsI; will work correctly but is this what you need?

Sincerely,
SPR

Yes, this is what I need as an upper value, but SAS doesn't accept the code..

Please give relevant code of you macro and error messages you got.
