StrCmpAlphabeticallyCI (FUN) ¶ FUNCTION StrCmpAlphabeticallyCI : INT Helper function for CmpInstancePaths: compares two strings alphabetically, ignoring case. See ASCII_to_SortIdx for the exact sorting order of all ASCII characters. Returns a value > 0 if identifier 1 comes after identifier 2, 0 if they are equal, and a value < 0 if identifier 1 comes before identifier 2.
