Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     string1                 The first string.
 
     string2                 The second string.

     string2-length          Length of the second string.
 
  Parameters on Exit:
 
     result-byte             Result of the comparison:
 
                              0 = The two strings have equal weights
                             -1 = string1 < string2
                             +1 = string1 > string2
 
     status-code             Indicates whether the routine was successful:
 
                              0 = success
                             40 = NLS module not initialized
 
     This routine can be used only from a program that was compiled with
     the NLS directive. For more details on National Language Support see
     the chapter National Language Support in your COBOL System Reference.
