1
Introduction to the
Spooler Subsystem
Provides detailed information on the Spooler
subsystem and its components that is of special
interest to programmers. All programmers
should read this section before reading any of
the other parts of this guide.
2
Using the Spooler
Interface Procedures
Describes the use of the Spooler interface
procedures. This section supplies examples of
spooling on three levels, along with COBOL
spooling and spooling from a NonStop process
pair for most of these levels. The latter
examples include discussion of zero and
nonzero sync depth.
3
Using the Spooler
Print Procedures, Print
Processes, and
Perusal Processes
Describes the use of the Spooler print
procedures. Information on print processes
includes reading the startup message, retrieving
and printing the spooled data, and
communicating with the spooler supervisor.
This section also discusses how to handle
device errors and PRINTREAD errors, gives
pointers on debugging print processes, and
covers combining data retrieval with spooler
communication.
This section also describes a user-written
perusal process which can access spooled data
without communicating with the spooler
supervisor.

Spooler Procedure
Calls
Presents the complete syntax and
considerations for all Spooler-related
procedures. The SPOOLERSTATUS Struts are
of particular interest to application programmers
for use in finding the status of Spooler
components.
A
Sample Print Process
Presents a sample print process.
B
Sample Perusal
Process
Presents a sample perusal process.
C
Spooler-Related
Errors
Describes errors codes returned by the Spooler
interface and by the print and utility procedures.
