Here's what I am assuming:
1) you have a separate file called "proc_one.pro" (all lower case) that
contains the "proc_one" procedure.
2) you have a separate file called "proc_two.pro" (all lower case) that
contains the "proc_two" procedure.
Based on that, why can't you just do:
read,rot,prompt='rot via proc one or two? (1 or 2)'
case rot of
1: proc_one,a,b,c
2: proc_two,d,e,f
endcase
Note I use an integer selector rather than typing out the actual name of
the procedure required (after a couple of tests, all that typing would
drive me nuts).
Once you get this working, then you might want to start to get fancier
using CALL_PROCEDURE, or EXECUTE, or similar.
cheers,
