Chapter 4. The Graphics Control Program
This chapter is intended to enable data processing professionals to evaluate
the function offered by the Graphics Control Program running in the work
stations.
To appreciate fully the flexibility the system offers, it is necessary to
examine not only the Graphics Control Program, but its relationship with
the rest of the system.
The IBM 3270-PC Graphics Control Program is an extended version of the
IBM 3270-PC Control Program, for use with the IBM 5279 and 5379
Displays. The Graphics Control program provides:
• All the function provided by the 3270-PC Control Program, such as the
ability to manage multiple sessions concurrently.
• Graphics capability on the four host-interactive sessions and the PC
session. This graphics capability includes support for graphics input
devices.
• A spool print facility that creates a graphics picture interchange
format file for subsequent printing by a utility of the control program
or for processing by other suitable application programs.
• Support for plotters attached to the work stations. A plotter can be
used either directly by a host application program or by a local PC
application program.
• Support for the programming language APL in alphanumeric host
application programs.
• Support for attachment to a host computer through a 3274 Control Unit,
with the alternative ability to use the IBM 5279 and IBM 5379 Displays
as stand-alone work stations.
The following sections deal with these topics.
