Changed it around using your tricky TR and it works. Thanks so much!

Assume R0 contains the return code of X'0000008B'.
After the CVD, RWORK (I assume it is 8 bytes long) contains
X'000000000000139C', which is the decimal equivalent of hex 8B.
>MVC M1CC-1(L'M1CC+1),=X'402120202020' MOVE IN EDIT MASK
I assume that M1CC has a length attribute of 5. After the MVC, M1CC-1 will
contain X'402120202020'.
>ED M1CC-1(L'M1CC+1),RWORK+5 CONVERT RET CODE TO CHAR
After this instruction, M1CC contains X'4040F0F1F3F9', which is the EBCDIC
(printable) equivalent of decimal 139.
>However, I want the return code to print as hexidecimal instead of decimal.
I tried the >following after these prior 3 statements:
>NC M1CC+1(4),=4X'0F'
After the NC, M1CC+1 contains X'00010309'. The NC changes the high-order
half of each of the four bytes to a X'0' and leaves the low-order half alone.
>TR M1CC+1(4),=C'0123456789ABCDEF'
After the TR, M1CC will contain X'00010309'. This is not EBCDIC, not
printable, not decimal, not hexadecimal, but instead a quasi-decimal.
>Why is it not translating the decimal to hexadecimal???
In order to translate decimal to hex, you have to do the inverse of the CVD.
I prefer to do it with the CVB instruction. You had hex in R0 to begin
with, then you converted it to decimal, then you mangled the decimal rather
than
converting it back into hex.
You want printable hex, so replace the CVD, MVC, ED, NC, and TR with the
following:
ST R0,FULLWORD
UNPK M1CC+1(9),FULLWORD(5)
TR M1CC+1(8),=C'0123456789ABCDEF'-X'F0'
After this, M1CC will contain X'F0F0F0F0F0F0F8C2', which will print as
0000008B.
Your NC and TR will work, but only if the original hex number is first
unpacked into twice as many bytes. If you use the tricky literal I used, you
avoid needing to do the NC instruction. After the UNPK, you can do either
your
original NC and TR or my tricky TR.
