Purpose
Function to compare two strings
Syntax
STRCOMPARE(<expC1>,<expC2>)
See Also
AT(), CHROVERLAP(), GETGID(), GETUID(), STRCMP(), STREXTRACT(), SUBSTR()
Description
The STRCOMPARE() function compares two strings, character by character, and returns true (.T.) if the characters in the first string <expC1>, are always greater than or equal to the equivalent characters in the second string <expC2>. The test continues up to the length of the shorter string.
This function is particularly useful in validation routines for controlling access to menu options.
Example
cUSERPRIVS = [YYYNNYNN] if strcompare(cUSERPRIVS,'NNNNNNNYN') SysMaint() else return endif
