3270-PC Functions
The Graphics Control Program, like the 3270-PC Control Program, provides
the operating environment and facilities of a professional work station:
•
Up to seven concurrent activities are possible: four 3270
host-interactive sessions, two local notepad sessions, and a single IBM
PC DOS session.
•
Base or extended color, extended highlighting, and storage for
programmed symbol sets that host application programs can use for
special characters.
•
Advanced screen management that allows windows to be defined on the
display screen for each session. A window can reveal all or a defined
part of each session, and can have any size and position, up to
full-screen size. A window can also be given any color that the user
chooses. It can be enlarged or hidden, and the session it reveals can be
scrolled behind the window.
•
The ability to copy a block of alphanumeric data within or between
sessions, except for the IBM PC DOS session.
•
A keystroke record-and-playback function that enables the user to
record frequently used keystroke sequences for subsequent playback.
•
The ability to save and restore the current work station and control
program environment (for example, the screen layout definitions, any
keystroke recordings, and the contents of notepads).
•
The ability to print the alphanumeric contents of a host-session on a
printer attached to the 3274 Control Unit.
•
A file transfer facility that, in association with the IBM 3270-PC File
Transfer program products, allows data in ASCII, EBCDIC, or binary
format to be exchanged between work station and host.
Graphics Capability
The Graphics Control Program provides interactive graphics functions that
can be used by both host-interactive and local PC application programs.
The following sections of this manual describe various aspects of these
functions:
•
Vector graphics
•
Graphics input
•
How graphics function is distributed in the system
•
The relationship between alphanumerics and graphics.
