Hai ,
While doing an MQGET or MQPUT in OS/390 should the message BUFFER be of pic x()
Can it be pic 9()? Thatis can the message buffer be declared as numeric or comp ?
Thanks in advance

Buffer is always Char data. It may contain though, numeric or non-numeric data.
Cheers.

Essentially, the buffer is just a bit string as far as MQ is concerned - on the MQPUT for example, you pass the buffer by address and tell MQ the length of the data starting at that address. On the MQGET, the buffer just has to be an area big enough to hold the bitstream of the message. What you do with it AFTER that is up to you.
However, as Kumar says, always make the buffer a char string and you will not go wrong.

The data may not get converted properly on the other side if you use comp. Much safer and easier in the long run to move all your comp fields into Pic X fields, then MQPUT.
