There is only one "nuance" in program parameter passing normally and that is
to realize that if a program is called from the command line that numeric

covered in the FAQ. Quite why some shops adopt the char method of passing
parms and the resulting error prone code that goes with it is a mystery to
me.

Jon, I know that _you_ understand this, but since this is one of my hot buttons I'll kick in my opinion for the greater good. Passing by character doesn't help either because long character fields have the exact same problem when passed as literals. Long is greater than 32 characters. It's in the FAQ. Search for 'garbage' http://faq.midrange.com

Jon is absolutely right that you really ought to pass the actual data type rather than force everything to character and back. Let the compiler help you with your coding chores...
