So, as you want 2 ampersands you need to use 4, and thus I suggest trying:
IF &SUBSTR(&K,&L)=A THEN SET &X=&STR(&X) &&&&OPTA
ELSE IF &SUBSTR(&K,&L)=B THEN SET &X=&STR(&X) &&&&OPTB
ELSE IF &SUBSTR(&K,&L)=C THEN SET &X=&STR(&X) &&&&OPTC<
I've tried things like that; it is absolutely not that simple. I just tried this
solution; it sets X to a single ampersand concatenated only to the last
expression. For example, if the user enters "ABC", the result is "&OPTC".
There's something more to it than just doubling the ampersands.
You're right; sorry. That will work for the first assignment, but not
the subsequent times. Lizette's idea of using &NRSTR or &SYSNSUB is
probably what you need.
... THEN SET &X = &SYSNSUB(1,&X) &&&&OPTA
or possibly
... THEN SET &X = &SYSNSUB(1,&X) &NRSTR(&&OPTA)
