Spooling—Level 3

?list

PROC root MAIN;

BEGIN

! Declarations

INT collector [0:11] := "$S #LP3 LP3 ",

! contains the file name of the collector and

! location in internal format

collectnum,

! contains the file number returned from OPEN

location [0:7] := "#LPRMT3 ",

! contains the new location for the job

flags := %B0100100000000000,

! contains the bit pattern for the flags parameter to OPEN

! and CHECKOPEN

line [0:39],

! contains the line of data to spool

length,

! contains the number of bytes to write from line

err,

! contains the CHECKOPEN back error or the CHECKPOINT

! status word

sperrnum,

! receives spooler error code

.buffer[0:511],

! this is the level 3 buffer

bytecount;

! contains the number of bytes written to the buffer

! Open file to collector, and check for errors.

CALL OPEN( collector, collectnum, flags);

IF <> THEN CALL error;

! CHECKOPEN successful open of the collector

CALL CHECKOPEN(collector,collectnum, flags,,,, err);

! Check for a CHECKOPEN error

IF <> THEN CALL cherror(err);

! Checkpoint call to SPOOLSTART (in this example none of the

! parameters to SPOOLSTART have been computed so this checkpoint

! is not necessary, but most practical programs would need this

! checkpoint)

CALL CHECKPOINT( location);

! Call SPOOLSTART to specify new job attributes and level-3

! buffer

! location #LPRMT3

! form name blanks (default)

! report name user's name and group name (default)

! number of copies 1 (default)

! page size 40

! flags

! hold off

! holdafter on

! NonStop bit on

! priority 7
