The Test program:
/ REXX /
Parse version v; Say v
x=3
y=22
Say 'x>y ->' (x>y)
Say 'x>>y ->' (x>>y)

J:>rexx sc
REXX-ooRexx_4.2.0(MT)_64-bit 6.04 22 Feb 2014
x>y -> 0
x>>y -> 0

J:>regina sc
REXX-Regina_3.9.1(MT) 5.00 5 Apr 2015
x>y -> 0
x>>y -> 1
I think that Regina is correct

    It would seem in the case where “3”>>”22”, that failure would occur because “3” is the shorter string, and therefor can never be greater than “22”, even if y was “00”. Strict comparisons are always string comparisons not numeric comparisons.

    my $0.02.

      I don't buy your change :-)

      try x3>>x22

      because “3” is the shorter string, and therefor can never be greater than
      “22”, even if y was “00”. Strict comparisons are always string comparisons not
      numeric comparisons.

    Walter, this was fixed for 5.0 - see [bugs:#1358]

    Strict comparisions always carry out a simple character-by-character comparison, without attempting to perform a numeric comparison.

    Walter: Don't forget tthat you can use Gil's orxver.bat to create a backup of your current version that it
    can restore in place of 5.0.0 while saving it too!
