CONVENTIONS:
MEMORY
REQUIREMENTS:
a. Read the message from the current control-message medium.
b. Analyze the syntax of the control message.
c. Convert any parameters in the control message to the internal representa-
tion appropriate to the parameter and store the parameter values obtained
in specified memory location(s}.

function code in the control message.
If errors are detected during this process, an appropriate error message is
typed out, the message contai ni ng the error is ignored, and the routine at-

reported):
BRU RDMSGR
with a valid unit, channel, and I/O subroutine address in the Unit
Assignment Table for control messages (QMSG).
