-- Routine: WCompSz(psz1,psz2)
-- Description and Usage:
Alphabetically compares the two null-terminated strings lpsz1 and lpsz2.
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 lpsz1 precedes lpsz2, and
a non-zero positive number if lpsz2 precedes lpsz1.
-- Arguments:
psz1, psz2 - pointers to two null-terminated strings to compare
-- Returns:
a short - 0 if strings are equal, negative number if lpsz1 precedes lpsz2,
and non-zero positive number if psz2 precedes psz1.
-- Side-effects: none
-- Bugs:
-- History:
3/14/83 - created (tsr)
6/12/86 - Kanji Version (yxy)
