(untested, otherwise you'd get code)

use function $0c of _exec_pg3 to input a string.  this will give you a
temporary string var with its name in op1.
do a findsym on that variable & change the variable type in the vat to
equ.
save the name of the temporary variable someplace

store the values you need to their respective variables using _stoother. 
load value to op1, push op1 (rst $18?), load the var name to op1, call
_stoother

load the equation name back into op1, then call one of the parse
functions.  i don't know which one, maybe good ole _PLOTPARS 
your result _should_ be in op1 (i think...)

repeat as desired.  you might want to clear the temp vars when you're
done.  i don't remember the name of that function right now :)  check the
83+ docs.

(i assume people don't ask for basic code on the asm list...)
