IF then else

[Bal]

Why below append and contents prod does not work inside do loop?

........................................

%if &error='NO' %then %do;*Macro error has 'NO'.
%let message=&message;*I have message defined aleady;
proc contents data=record;*I already have record dataset;
proc append base=updates data=record;
run;
%end;

If i run above code inside macro data 'record' does not append to the 'updates' table.

It will help to show the entire macro and how you assign a value to &error.

As a debug tool use:

options mprint symbolgen;

and then run the macro. The post the results from the log.

Does the macro variable ERROR contain the value NO or does it also contain the surrounding single quotes?

Your code is checking for the value 'NO' not for the value NO.

I have created NO as below:

call symput('error', 'NO');

Thank you very much. Problem was I put single quote. So this means we don't need any quote even if it is character value for macro variable. Now it's working without quote.
