* GOAL: Within a macro, you want to create a new variable name.
* It could then be used as a data set name, or a variable name to be assigned, etc.;
%macro newname(dset=,varname=);
* You have to make the new name before you use it in
* another data statement;
data _NULL_;
L1=CATS("&varname","_Plus1");
CALL SYMPUT('namenew',L1);
;
* Now you can use the variable name created by SYMPUT;
