Dollar Sign in RPG/AS400 variable name

I am looking at some code, some AS400 code; I see a variable declaration with a $ symbol in it. Does this have a special meaning?

D Q$test          S              8  0

Ostensibly this is a numeric variable 'test'; is Q$ a part of the actual name or does it have a special meaning for AS400/RPG.

Solution

  • It has no special meaning to RPG, just part of the name. Some programmers used some convention like those were local variables vs. those from database or display file but the meaning could be different in different companies.
