Agreed.
But I would question ‘gaining speed’. Assuming subprocedure is 10 times
faster than a dynamic program CALL then a 10-nanosecond  program call
becomes 1 nanosecond in subprocedure call. This change is not noticeable in
interactive applications and in most batch applications where the same
program is call for, say, only a few thousand times. Besides, if we exclude
the time spent on resolving calling procedure/program, the execution time
may be the same for both. This means that a 10-second run program will only
become a 9.99-sencond run procedure.

Regards.
