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
