Subprocedures at least give the programmer a hint about how to decompose
the routines properly (explicitly defined parameters.) In a subroutine
there's no mental brake advising you to "Stop! Don't add that new
function in there!" How many times have we seen a GETCRD BEGSR that
"gets credit rating" and as long as the subr did a CHAIN to CUSMAS,
why not add the code to update the A/R balance, and as long as we're hitting the
A/R balance, why not add code to modify the credit rating? All too soon,
there's a mess - it's all mainline code with EXSR substituted for GOTO.
There's no guarantee that your programmers will refuse to use global data
in a procedure, but I would argue that the new construct will encourage better
programming more than the old one will.
