Language Reference
KEYWORD-ALL Function
Returns a character value that indicates whether a string is a Progress keyword. This function returns all keywords and does not distinguish between reserved or unreserved keywords.
SYNTAX
expression
A constant, field name, variable name, or expression that results in a character string. If expression matches a Progress keyword, whether reserved or unreserved or valid abbreviation of a keyword, the KEYWORD-ALL function returns the full keyword. If there is no match, the KEYWORD-ALL function returns the unknown value (?).
KEYWORD-ALL is the same function as KEYWORD in Progress Version 6 and earlier. Use this function if you do not want to use Progress reserved and unreserved keywords as field names, for example.
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-ALL function always returns the unknown value (?).
EXAMPLEIn this example, the KEYWORD-ALL function tests the value of formname. If the user tries to use a keyword as a form name, Progress displays a message to try again.
NOTES
- Because KEYWORD-ALL 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.
- For SpeedScript, all Progress reserved keywords are also reserved for SpeedScript.
