/*---------------------------------------------------------------------------
-- Routine: WCompSzC(psz1,psz2)
-- Description and Usage:
    Alphabetically compares the two null-terminated strings psz1 and  psz2.
    Upper case alpha characters are mapped to lower case.
    Comparison of non-alpha characters is by ascii code.
    Returns 0 if they are equal, a negative number if psz1 precedes psz2, and
    a non-zero positive number if psz2 precedes psz1.
-- Arguments:
    psz1, psz2    - pointers to two null-terminated strings to compare
-- Returns:
    a short - 0 if strings are equal, negative number if psz1 precedes psz2,
    and non-zero positive number if psz2 precedes psz1.
-- Side-effects: none
-- Bugs:
-- History:
