RE: Pointer question (long)

Phil found the problem - passing a pointer to a pointer.

The reason I want to pass a pointer is becuase now one can MD5 any data
passed to it. One could pass a record format and get a fingerprint of the
whole record, or a data structure, etc, without being constrained to (RPG's)
character limits. I agree for most cases, one would only want to MD5
character data, but a little more effort makes the subprocedure much more
useful.

Lloyd,

Something about the convert() procedure seems odd to me.  It appears to be
trying to reference the address of a pointer.  That may not be the cause of
your error.  I'm not sure.

I'd suggest redefining the interface to your MD5 procedure to pass a
variable length string, rather than a pointer and a length.
