Hmmm, nothing found in the archive nor on the newsgroup. The last recorded activity for both was an entry from July. Perhaps the email address was incorrect or that list is\was not functional.?

I have a single XORSTR instruction that I would like to be able to
call in an ILE environment. I have no expertise in C, but I do have
the compiler here if that makes things easier. The instruction will
XOR one fixed length field against another. The length factor may be
variable.

Any suggestions where to start?

The SQL scalar string function XOR could be a worthwhile replacement?

For example, perhaps one of:

<code>

Exec SQL
VALUES xor( :c1 , :c2 )
INTO :c
;

/* varying */
Exec SQL
VALUES left( xor( :c1 , :c2 ) , :len )
INTO :c
;

/* hex */
Exec SQL
VALUES hex( xor( :c1 , :c2 ) )
INTO :c
;

/* varying and hex */
Exec SQL
VALUES left( hex( xor( :c1 , :c2 ) ) , :len*2 )
INTO :c
;

</code>
