SET TERM Command
ON
directs the TCP to accept the Break key function. If the TCP is executing a
SCREEN COBOL program in conversational mode, the terminal operator can
press the Break key to prematurely terminate ACCEPT and DISPLAY
statements. If the terminal operator presses the Break key while the TCP is
executing a DISPLAY statement, the terminal output stops and the DISPLAY
statement is terminated normally with the special register TERMINATION-
SUBSTATUS set to 1. If the Break key is not used, TERMINATION-
SUBSTATUS is set to 0 after the completion of a DISPLAY statement.
If the terminal operator presses the Break key while the TCP is executing an
ACCEPT statement that is coded with an ESCAPE ON ABORT clause, the
TCP stops accepting terminal input and terminates the ACCEPT statement
without changes to the working storage section. Pressing the Break key has no
effect on the TCP when the ACCEPT statement is coded without an ESCAPE
ON ABORT clause. If the TCP is not executing either of the preceding
statements, pressing the Break key has no effect on the TCP process.
OFF
directs the TCP to ignore the Break key function.
DIAGNOSTIC { ON | OFF }
specifies whether diagnostic screens are displayed to inform the terminal operator
when an error condition or termination occurs.
The SCREEN COBOL special register DIAGNOSTIC-ALLOWED is initialized to
YES or NO according to the value of this attribute. Screen recovery is invoked
following the display of a diagnostic screen.
If you omit this attribute, the default is ON.
ON
displays diagnostic screens. The first DISPLAY BASE statement in the
SCREEN COBOL program must have executed before this option can cause a
diagnostic screen to appear.
OFF
does not display diagnostic screens.
DISPLAY-PAGES number
specifies the depth of the terminal’s screen caching. DISPLAY-PAGES determines
the maximum number of screen displays that are stored in the terminal’s memory.
