/*************** macro varaiable *********************/

data works._RefDate_;

if  &refvar.  ge RFSTDTC then  AEENDY  =  &refvar. - RFSTDTC ;

run;

The macro varaible  AEENDT  has suffix "DT" DT should  be place by "DY"...  and  create the new variable.. "  In the above code i have hard code the new variable name "AEENDY ".""

Not sure what kind of dynamics you want, but can't you just use &refvar instead of the hard code variable name?

Hi,

Why do you want to put the variable name in a macro variable at all, I don't see any benefit?  All your doing is complicating the code.   If you really really have to use macro then put the base part of the variable in the macro and then append the additional part:

% let refvar = AEEN ;

/********************* creating new variable =AEENDY  *******************/

data works._RefDate_;

     set  _RefDate_;

     RFSTDTC =input ( RFSTDTC  ,YYMMDD10.);

     if  &refvar.DT   le RFSTDTC then  &refvar.DY  =  &refvar.DT - RFSTDTC + 1;

     if  &refvar.DT  ge RFSTDTC then  &refvar.DY  =  &refvar.DT - RFSTDTC ;

run;

Again though, this oesn't add any value, so why bother?
