.... %let new=VAR1; assigns the string 'VAR1' to the macrovariable &new.
No, the Data step assignment VAR1=....; will not execute until after the
Macro executes. The Macro assignment %let var1= ...; assigns a character
string from the right side of the '=' to the macrovariable &var1. Were I
you, I'd hold off on writing Macro loops until I developed a better
understanding of Macro processing. Take a step back and study the order
of execution of elements in a SAS program vector.

If you are trying to write a Macro that will substitute a value for a
parameter in a reporting procedure, why not describe what you want to do
in a SAS-L post. A number of Macros already exist and you could learn a
lot from studying appropriate ones that SAS-L participants are willing
to share.

Thanks Sig,
but the problem here is I want to create &new equals
to "11" ,"12","13".That is VAR1='11' and the &new=11
or
&new=var1.

So Is there a way I can do this:


%let var1=%str('1'||"&j");

I cannot use CALL SYMPUT because I have to use the
values in the same datastep.


Thanks
Monal
