Re: If MSGTYPE has *NEXT or *PRV specified, MSGKEY is required.

Thanks for the replies :-)

I put in what Gary suggested.

2 things -
In debug, after the first rcvmsg call, the value of the keyvar looks
like gibberish,
(reverse img chars etc) Shouldn't this be clear, legible text?

2nd thing, it now crashes, right away, on the second rcvmsg call
(the one with msgkey), as per message below.

Message . . . . : Application error. CPF2410 unmonitored by GARMON at
statement 0000000204, instruction X'0000'.

Any ideas?

Gonna do some trial and error and reading-up,
(not necessarily in that order)
