Open considerations

The following considerations apply to opening printer files for spooled output:

• The output queue should be created for the type of output your program produces so that system operator intervention can be kept to a minimum while a printer writer is producing output. You should consider the following when creating an output queue:
  • What form of output is being produced (printer or diskette).
  • What kind of forms the output is printed on.
  • What kind of protection you want to place on your data. (Do you want someone else to be able to display your data?)
  • How many job separators you want.
• The SCHEDULE parameter specifies when output is to be made available to a printer writer. When a printer writer processes a specific file, it is dependent on things such as:
  • When the writer is started
  • Other output files on the queue
  • If the writer or the output queue is being held
• The parameters specified to produce output are saved until they are used by the writer.
