KEYWORD Function
Returns a character value that indicates whether a string is a Progress reserved keyword.
SYNTAX
expression
A constant, field name, variable name, or expression that results in a character string. If expression matches a Progress reserved keyword or valid abbreviation of a reserved keyword, the KEYWORD function returns the full keyword. If there is no match, the KEYWORD function returns the unknown value.
In some cases, the abbreviation for a keyword is also a keyword. For example, if expression is “def” (the abbreviation for DEFINE) or “col” (the abbreviation for COLUMN), the KEYWORD function returns the values “def” and “col”, respectively.
If you use Progress Run Time, the KEYWORD function always returns the unknown value (?).
EXAMPLEIn this example, the KEYWORD function tests the value of formname. If the user tries to use a reserved word as a form name, Progress displays a message to try again.
NOTES
- Because KEYWORD recognizes abbreviations, it does not distinguish between FORM and FORMAT or between ACCUM and ACCUMULATE.
- This function returns the unknown value (?) for colors and most data types, as well as all unreserved keywords. See the "Keyword Index" in this manual for a list of Progress reserved and unreserved keywords.
- KEYWORD is less restrictive than the KEYWORD-ALL function. Use this function if you do not want to use Progress reserved keywords as field names, for example.
- SpeedScript — All Progress reserved keywords are also reserved for SpeedScript.
