Considerations
data-filenum input
INT:value
is the file number of the data file containing the started job.
Considerations
The following considerations apply to the use of the PRINTSTART[2] procedure:

In addition to containing control information for the job, the PRINTREAD procedure
uses job-buffer to store a block of spooled data.

PRINTSTART[2] is called once for each job started on a device.

The job buffer should not be altered by the print or perusal process.

A spooler job file can be initialized for reading by passing its file number as data-
filenum. In this case, neither PRINTCOMPLETE[2] nor SPOOLEREQUEST[2]
needs to be called prior to calling PRINTSTART[2] to initialize print-control-
buffer.

You can use PRINTSTART to access jobs that reside in the D41 and later releases
of the spooler only if they are in the form of file code 129 job files; otherwise, you
must use PRINTSTART2. If the files do not have a file code of 129, you will receive
file system error number %14015.
