Can you please explain why SAS interprets "≤" as "=" after execution in a macro or in proc report?
For example
%let a= ≤ ;
%put a is equal to &a;
The SAS log shows the following message:
SYMBOLGEN: Macro variable A resolves to =
a is equal to =
I also used quoting/masking functions, but it didn't help.
≤ is not part of the standard ASCII character set.
It may be the case that the SAS Editor doesn't support extended character sets, e.g. UTF-8 or Unicode.
When I copy/paste the ≤ symbol from my browser into SAS Editor, it becomes the = character.
If you wish to do a less-than-or-equals logical comparision in datastep or macro, simply use <=.
