Re: Constants in RPG

Hi, David:

I concur with Scott's comments, in this regard.

So-called "Hungarian Notation" was invented at a time when the C language was essentially a type-less language; C had no type-checking -- this was well before the ANSI standard for C was developed. During the process of creating the ANSI Standard for C, strong type-checking and other features were added to the C language definition.

I've never seen much value in Hungarian notation, myself.

So I tend to use a prefix that relates to the service program. Each service program in our system has a unique prefix, like say, PURCH is used for the purchase order service program. the constants (as well as prototypes, data structure templates, module names, etc) are all prefixed by PURCH.. and you have PURCH_SUCCESS and PURCH_FAIL. That way, it never conflicts, because other service programs don't start with PURCH.

To me, that's far more valuable than hungarian notation.

I also prefer to type my constant names in ALL_UPPER_CASE, and type my variables in MixedCase or lowercase. That way, there's a visual clue that you're working with a constant vs. a variable.
