hi,

i am not sure if i am understanding what you need, but why not use the
in= option? it follows the general form,

data work.two;
   set data work.one in='a';
run;

so what happens is that your data set two now has a flag variable
added..which has a value of 'a'. then you can use call symput to
retrieve the value of whatever variable you want..

not sure if this is what your after, hopefully it helps,

thanks, nevin
