Sysgen type
What it does . . .
Mini
Existing operating system is modified in a manner that does not
require new system file input or patching. For example, an
existing feature is deactivated or reactivated, or a specification
that is transparent to the operating system is changed.
Update
Existing operating system is upgraded to include new features
or is replaced with a new version of the system. During this
process, some or all of the existing system files on the system
disks are replaced with new files; user files are not affected.
Full
New operating system is built on empty system disks, such as
new or used disks that have been cleared and formatted prior
to system generation.
Command statements and files
You use Print Description Language (PDL) command statements
to describe data layout and provide instructions for data
placement on a page. You can use PDL command statements
whether or not you use an FDL-created form. The .JSL file
contains PDL statements which define the format of the input,
the process requirements, and the format of the printed output
you want. When you compile a .JSL file, it creates a .JDL file that
the system uses when you print your job.
Within a .JDL file, you can have one or more unique definitions
for different processing features, output formats, and tape
formats. Each set of unique definitions represents a job and is
called a JDE file or a JOB.
You must use a .JDL file when you print on the LPS. You can
request specialized printing functions using PDL statement
commands in addition to the .JDL file.
Reference
Refer to the Xerox 4050/4090/4450/4650 LPS Print Description
Language (PDL) Reference, the Xerox 4050/4090/4450/4650 LPS
Operator Guide, and the Xerox 4050/4090/4450/4650 LPS Forms
Creation Guide for more information.
The Operating System Software (OSS) provides several basic .JSL
files: For example, ENET.JSL is provided for printing Ethernet jobs,
ONLINE.JSL is provided for printing online jobs, XEROX.JSL is
provided for printing magnetic tape jobs, and so forth. To meet
specific application needs, you can copy and modify any OSS-
supplied .JSL file.
All Xerox LPS offer the LPS Editor utility as a standard feature.
This feature allows you to create and modify program source files
such as .JSL and .FSL files.
The LPS Editor allows you to enter the program source file into
the system, thus entering forms into the system as data. You use
the Forms Description Language (FDL) commands to design
forms with the ability to use variable data.
