GOAL:
When you can use Progress keywords and when you cannot use them
FACT(s) (Environment):
Progress 4GL
FIX:
Within Progress, some keywords are reserved.
A keyword is:
A word with a predefined meaning in the Progress language.
A reserved keyword is:
A word that has a special meaning in Progress and cannot be
used as an identifier.
A list of keywords can be found in the Keyword Index chapter of the
Progress Language Reference: Widgets, Handles, Attributes & methods, Events & indexes. This list also provides you with information about whether or not a keyword has been designated as reserved or "non-reserved".
In order to determine whether or not a word is considered to be a Progress keyword (if you do not have access to the Progress Language Reference manual), use one of the following functions:
- The Progress function KEYWORD() tells you if a string is a
reserved keyword.
- The Progress function KEYWORD-ALL() tells you if a string is a
keyword.
Progress Reserved Keywords should not be used in procedures as object
names (this includes tables, fields, frames, variables, streams, etc).
If you attempt to use a reserved keyword, the following error is
displayed:
Error
This name is a PROGRESS keyword.
Please enter another name.
If you are migrating from one version of Progress to another and find
you need to use a reserved keyword, you can use the Keyword Forget
List (-k) parameter at startup. Progress suggests to use this startup
parameter only until the reserved keyword can be removed from your application.
