John, I'm a little confused now ... Todd said that his comparison returned 'match'. If REXX executed a comparison of two equal-length character strings, then a 'match' - result would be incorrect. Only if REXX interpreted the two character strings as numerical values in exponent notation (0**0 and 0**8) and performed a numerical comparison, would a 'match' - result be expected. But why? That's not logical. Todd coded two quoted character strings, didn't he? Could someone please run a TRACE and post the results? I can't at the moment. This really puzzles me.

Ulrich, As long as his intent is a simple equality/inequality test, "=="/"<>" will work fine, in so far as the offsets are both presented with the same length and in the same case. A requirement for x2d(...) will only arise if the offsets are presented with the possibility of differing lengths, differing cases, or if a comparative magnitude test is required (<, <=, >=, or >).

Todd, What is your intent with this comparison? Do you want to compare two quoted character strings or do you want to compare the numeric (hexadecimal) values? If the latter, shouldn't you have coded either offset1 = "0000E0"X; offset2 = "0000E8"X; Or offset1 = x2d("0000E0"); offset2 = x2d("0000E8"); instead?
