Subject:      Re: macro q again

In response to the idea that &dat must have quotes around the value because of code like: %IF &DAT='UN' %THEN %DO;

the substitution of code:

%if &dat=UN %then %do;

Will work just as well if you omit the quotes from the assignment statement. for a line like: IF SUBSTR(MONTH,1,2)=&DAT

the substitution of code: if substr(month,1,2)="&dat" will work just as well when there are no quotes in the macro value.

The point is, that with macro variables you can go either way. However, it is easier to leave the quotes out of the macro value because then you won't have to use quoting functions later on.
