I believe there a choice here for CLIST. That is NRSTR rather than STR. If
you look in the TSO/E CLIST manual you will find a section on Preserving the
Double Ampersand.
&NRSTR prevents more than one level of substitution on a variable;
&STR prevents evaluation of expressions
&SYSSCAN can be used to set the number of levels of symbolic
substitution, including a value of 0, which suppresses
substitution completely until you reset it
&SYSNSUB works like &SYSSCAN for a single expression
I seem to recall that there is another function in CLIST that controls the
number of times a variable is interpreted, but I drawing a blank at the
moment as to what that is.

READ L
DO &K=1 TO &LENGTH(&L)
IF &SUBSTR(&K,&L)=A THEN SET &X=&X OPTA
ELSE IF &SUBSTR(&K,&L)=B THEN SET &X=&X OPTB
ELSE IF &SUBSTR(&K,&L)=C THEN SET &X=&X OPTC END WRITE &X
