RCVEXIT(string)
Channel receive exit name.
On platforms other than Tandem NSK, if this name is nonblank, the exit is
called at the following times:
v Immediately before the received network data is processed.
The exit is given the complete transmission buffer as received. The
contents of the buffer can be modified as required.
v At initialization and termination of the channel.
On AIX, HP-UX, OS/2 Warp, Sun Solaris, and Windows NT, you can
specify the name of more than one exit program by specifying multiple
strings separated by commas. However, the total number of characters
specified must not exceed 999.
On OS/400, you can specify the names of up to 10 exit programs by
specifying multiple strings separated by commas.
On other platforms you can specify only one receive exit name for each
channel.
The format and maximum length of the name is the same as for MSGEXIT.

remote queue manager are given to the exit.
