Hello

 I am using a macro variable as a title value.

Why this code is working while title should be in a quotation marks??
I expect that the code should be  title "&mtitle"

But I see that  &mtitle is working also without  quotation marks

 

Data aaa;
input name $ Y;
cards;  
Joe  20
Yulia 30
;
run;

%LET mtitle = Macros are my game;
proc print data=aaa noobs;
title   &mtitle 
Run;

Likely backwards compatibility for really old versions of SAS. You're also missing a semi-colon at the end as well.

As often with SAS, the answer is "for historic reasons".

 

Tip: For compatibility with previous releases, SAS accepts some text without quotation marks. When writing new programs or updating existing programs, always enclose text in quotation marks.
