Using msgnbr or msgnbrchar with cvtch() throws C2M3001 so I know I
have to convert msgnbr to a hex value.

My quandary is how in the world do I convert integer 9488 to hex
value x'2510' so I can use cvtch() to convert x'2510' to character
value '2510'?

cvthc() is the one that takes x'2510' and converts it to '2510'. cvtch() goes the other way.

D cvthc PR extproc('cvthc')
D long_target * value
D short_src * value
D tgt_length 10I 0 value
D msgid ds
D prefix 3a
D num 4a
/free
prefix = facility;
cvthc (%addr(num) : %addr(msgnbr) : 4);

I have a new mnemonic for these functions to help me remember what h and c stand for. "hex" is a small word and "character" is a long word, so cvthc, convert from hex to character, is the conversion that goes from small to big, 2 byte x'2510' to 4 byte '2510'. And vice versa.
