Pressing the Terminal Break Key
The QUERY-COMPILER-LISTING file and the QUERY-REPORT-LISTING file are
described under Generic Files on page 2-10. The ?OUT command file is described on
page 6-14.
Pressing the Terminal Break Key
Enform Plus acknowledges the terminal Break key whenever the input file is a terminal.
The input file is a terminal under the following conditions:
•
The IN option is omitted from the ENFORM command making the home terminal
the default input file.
•
The terminal (whether the home terminal or another terminal) is the file specified in
the IN option of the ENFORM command.
Pressing the terminal Break key on any terminal, including the home terminal, has no
effect unless the terminal is the input file.
The current activity determines the action taken as follows:
•
Pressing the Break key when Enform Plus is processing a query, producing a report,
or producing output from the ?SHOW command, returns the terminal to the Enform
Plus prompt (>). Query execution and any output terminates. If you press the Break
key while Enform Plus is performing a sort operation, Enform Plus does not respond
to the Break key until the sort operation finishes.
•
Pressing the Break key when commands or statements are being entered (either
directly or indirectly), returns the terminal to the TACL prompt (nn>).
•
Pressing the Break key when you have entered the Editor process from the Enform
Plus prompt has the same effect as when the Editor process is entered from the
TACL prompt with one exception: pressing the terminal Break key at the Editor’s
prompt (*) has no effect.
If the @BREAK-KEY option variable (described on page 5-48
) is set to OFF, pressing the
Break key returns the terminal to the TACL prompt. It terminates neither output nor
query execution. In this case, Enform Plus continues to run and any output directed to
the terminal is temporarily interrupted. The TACL PAUSE command can be issued to
resume output.
Logical File Assignments
Enform Plus allows logical file assignments to be made either before or after the TACL
ENFORM command is entered. When the logical file assignment is made from within the
Enform Plus subsystem, use the Enform Plus ?ASSIGN command described on page
6-3
. When the logical file assignment is made before the ENFORM command is entered,
use the TACL ASSIGN command to either associate a physical file with a dictionary
record description or to assign some form of Enform Plus output to a generic file.
When Enform Plus is used in noninteractive mode, the TACL ASSIGN command
overrides an Enform Plus ?ASSIGN command that is part of the input file. When
