OUTPUT [OPCODE 067]
22.116 OUTPUT [OPCODE 067]
FUNCTION
Sends data from memory to an initialized channel. Use FILOP. to
perform an OUTPUT for an extended I/O channel. The OUTPUT monitor
call is the same as the OUT monitor call, except that OUT takes the
error return if any error bits are set in the I/O status word, and
OUTPUT ignores the error bits and has only~one return location.
CALLING SEQUENCE
OUTPUT channo,addr
return
In the calling sequence, the program supplies the following variables:
o
o
channo is the number of an initialized channel.
addr is one of the following:
If the channel was initialized for dump mode,
is the address of an I/O command list.
then addr
In buffered mode, addr contains the address of the .BFHDR
(header) word of the buffer to be used. If you give addr
as 0, the next buffer is used.
If the channel was initialized for buffered mode, then
addr is the address of the second word of the next buffer
to be used; if you give 0 (the normal case), the next
buffer in the ring is used.
RETURN
Data is output to the device on the channel.
