Re: Using prototypes...

[Loyd Goodbar <loyd@xxxxxxxxxxxxxx>]

It isn't a matter of clinging to the past, but mindfulness of
documented length restrictions. I've gotten into the habit of putting
source into a file called SOURCE. I must remember to keep text in
members of type QMQRY and SQL under 78 positions (I think). Regardless
of source length, RPGLE is limited to 100 (94 usable) positions, even
in free form.

Also, how do you segregate a command named FOO from it's command
processing program FOO? With REXX, the defaults are QREXSRC/*CMD. It
is easy to changevduring compile, but sometimes easier to keep default
for expediency.
