OBJECT-COMPUTER Paragraph
TERMINAL IS
specifies whether the program is a screen-oriented requester program that
communicates with a terminal or a message-oriented requester program that
communicates with an intelligent device. If the TERMINAL IS clause is omitted,
the program is assumed to be a screen-oriented requester program operating in
block mode; the requester program can run on any of the block mode terminal
types listed for a screen-oriented requester program. However, features unique to
a particular terminal cannot be used if the TERMINAL IS clause is omitted.
For a screen-oriented requester program you can specify the type of terminal for
which the requester program is intended and the type of communication, block
mode or conversational.
T16-6510
T16-6520
T16-6530
T16-6540
specify the particular terminal operating in block mode.
•
Program units compiled for a T16-6520 terminal can be run on a T16-6530
or T16-6540 terminal.
•
Program units compiled for a T16-6530 can be run on a T16-6540.
•
Program units compiled for one terminal type and run on another terminal
type can use only those features available for the compiled terminal type.
IBM-3270
specifies an IBM 3270 type terminal operating in block mode.
CONVERSATIONAL
denotes any of the following terminals operating in conversational mode:
6510, 6520, 6530, or 6540 type terminals, IBM 3270 type terminals, or any
other device that the operating system recognizes as operating in
conversational mode.
Features unique to terminal types in block mode are not recognized for the
same terminal types in conversational mode.
For Intelligent Device Support (IDS), the message-oriented requester program can
communicate with AM3270, SNAX, TERMPROCESS, AM6520, X25AM, or a
Guardian operating environment process. The TERMINAL IS clause specifies
whether the terminal communicates in conversational mode or block mode.
INTELLIGENT-0
specifies conversational mode. WRITEREAD I/O protocol: write to a device
and wait for a reply in conversational mode.
