Re: Coding Constants

[Charles Wilt <charles.wilt@xxxxxxxxx>]

No, it's pretty easy...

One thing to consider, what happens if you've got this today

d cSUCCESS        c                      '00000'

and tomorrow you what to start using constants in a module that needs
d cSUCCESS        c                      '       '

So you might want to be a bit more specific...
d cSQL_STATE_SUCCESS...
d                 c                   '00000'

and group related constants using a prefix
d cSQL_STATE_CURSOR_NOT_OPEN...
d                 c                   '24501'

d BUSINESS_TYPE_FIRSTAID...
d                 c                   '01'
d BUSINESS_TYPE_FIRE...
d                 c                   '02'

d EXCHANGE_TYPE_HYDRO...
d                 c                   'H'
d EXCHANGE_TYPE_INTERNAL...
d                 c                   'I'

Finally, a piece of advice...when defining your constants, get in the
habit of always using two lines.  That makes it easier to rename it 10
minutes later when you think of a better name.  :)  Plus I think it
looks better if they are all two lines.

HTH,
Charles

That way I'm sure to use the same names and hopefully gain some time. You've guessed it, we aren't putting our constants in copybook members. We do have one copybook member that contains a lot of general constants with no particular relation to each other. Here's an example :
