   1A slow day today so here is a revised itest command with provisional
   2support for comparing strings as well :-))
   3
   4Now table driven to allow the operators
   5-eq, -ne, -lt, -gt, -le, -ge, ==, !=, <>, <, >, <=, >=
   6
   7Uses the expected command modifier for integer compares of width 1, 2 or
   84 bytes of .b, .w, .l and the new modifer of .s for a string compare.
   9String comparison is over the length of the shorter, this hopefully
  10avoids missing terminators when using an indirect pointer.

  12eg.
  13if itest.l *40000 == 12345678 then; ....
  14if itest.w *40000 != 1234 then; ....
  15if itest.b *40000 >= 12 then; ....
  16if itest.s *40000 -eq hello then; ....
