See the Guardian Programmer’s Guide and the Guardian Procedure Calls Reference
Manual for additional information about $RECEIVE processing.
Maximum^syncdepth
(value 4)
The server can support requesters that issue up to four I/O requests
to the server between calls to a checkpoint system procedure such
as CHECKPOINT, CHECKPOINTX, CHECKPOINTMANYX, and so
forth.
Maximum^reply
(value 24 bytes)
The server can store replies that are up to 24 bytes long, as shown
in each Reply table.
Receive^depth The server’s Received Message Table holds messages received
from $RECEIVE for which a REPLYX has not been issued. Because
the table shows that it now holds eight messages, the operating
system rejects any subsequent messages from requesters until the
server calls the CRE_Receive_Write_ function to reply to one of the
messages.
