True or False replace 0

Unstefan — Fri, 16 Nov 2018 13:28:20 GMT

Hello SAS

I have de following database :

NOCONT	prod	DPD_0	DPD0	CDSITC1	STARE1	TOTAL11	DPD_1	DPD1	Scadenta	dtcsts03	DPD_WCS_risc	WCS	DPD_wcs	diferenta
500000001	CR	0	B0. 0	1	A	2925.07625	9	B1. 1-3	22	10/22/2018	39	11/30/2018	39	0
500000005	CR	8	B1. 1-30	1	A	667.75375	39	B2. 31-			69	11/30/2018		0
500000007	CR	0	B0. 0	1	A	0.48	9	B1. 1-3	22	10/22/2018	39	11/30/2018	39	0

DPD_WCS_risc represents DPD_1 + 30

DPD_ WCS represents the difference between WCS and DTCSTS03

diferente represents dpd_wcs_risc=dpd_wcs

normally in excel the results will be TRUE , FALSE or #n/a

after I run my code the results is 0 either is true or false , and in column DPD_WCS where the value is missing appear a dot (.)

both dpd_wcs_risc and DPD_risc are numerical

can someone please help me with a suggestion

I want to replace the missing values in DPD_wcs with #n/a or blank

I want to replace de diferenta values with true , false and #n/a or blank

here is my code :

data RRL;

set work.roll_rate_2;

DPD_WCS_risc=DPD_1+30;

WCS='30nov2018'D;

format WCS mmddyy10.;

DPD_wcs=wcs-dtcsts03;

diferenta=DPD_WCS=WCS;

run;

SAS is not Excel, the If's don't work the same, you need to use the else statement if the if statement evaluates false.

if a = b then c;

else d;

not a=b=c;

Hi there,

You can use PROC FORMAT to define how you want your variable to be printed.

proc format;
value myfmt .='n/a'
0='false'
other='true';
run;

Then to print the formatted data, you would do something like this:

proc print data=education;
   var mydiffval; #include all variables you want to see in the printed output
   format mydiffval myfmt.;
run;

There's an example like this in the doc for PROC FORMAT.

Alternatively, if you want to save the formatted value, you can use a second DATA step to create a new data set and assign the format to your variable.

Hope this helps!

What the others said, and here my suggestion for the format code:

proc format;
value boolean
  0,. = 'False'
  other = 'True'
;
run;

data test;
input value;
format value boolean.;
cards;
0
1
.
-1
3
.3
;
run;

The format reproduces exactly what SAS considers to be true or false.

As for your code, I suggest a very slight change:

diferenta = (DPD_WCS = WCS);

This makes it obvious what is meant here.

You can use IFC() function.

data roll_rate_2;
infile datalines dlm=',' dsd missover;
input NOCONT prod: $8. DPD_0 DPD0 : $8. CDSITC1 STARE1: $8.TOTAL11 DPD_1 DPD1 : $8.Scadenta dtcsts03 :mmddyy10. ;
format dtcsts03 mmddyy10. ;
datalines;
500000001,CR,0,B0. 0,1,A,2925.07625,9,B1. 1-3,22,10/22/2018
500000005,CR,8,B1. 1-30,1,A,667.75375,39,B2. 31-,,
500000007,CR,0,B0. 0,1,A,0.48,9,B1. 1-3,22,10/22/2018
;
run;

data RRL;
set work.roll_rate_2;
DPD_WCS_risc=DPD_1+30;
WCS='30nov2018'D;
format WCS mmddyy10.; 
DPD_wcs=wcs-dtcsts03;
diferenta=ifc(DPD_WCS=DPD_WCS_risc,1,0);
run;

Note: Missing values for numerics are represented by (.) dot in SAS.

thank you

sorry for my late answer , I have a lot of work to do , I'm at the very beginning of SAS.

I try to automatize some process that I have to do daily. it seems more hard in SAS but the time is priceless
