These terminal commands can be used to interrupt the current operation.
This document covers the following topics:
Note:
The terminal commands %% and
%. will be ignored if the profile parameter
ESCAPE is
set to OFF.
If you enter %% in any field on the screen,
the currently active Natural program will be terminated immediately and Natural
will return to command input mode. If you enter %%
in command input mode, the Natural session will terminated (equivalent to the
Natural system command FIN).
%% has the following effects:
The contents of the Natural stack will be deleted.
Any logical database transaction currently being processed is backed out.
The source program currently in the work area of the editor will not be affected.
In batch mode, %% may be used to set restart
points in the input files and thus ensure the synchronisation of the input
files in the case of an error.
| Command | Function |

CC=ON |
If the Natural profile parameter CC is set and an error
occurs during the compilation/execution of a Natural program in batch mode, the
input data stream for the SYNIN and OBJIN input files
will be flushed until a line containing %% in the
first two positions is encountered (if no %% is
encountered, it will be flushed until the end-of-file is reached). In addition,
the contents of the Natural
stack will be deleted.
If more data are available in the input stream, Natural resumes
processing with the line after |
CC=OFF |
Any %% in the input data will be
ignored.

Online, %. is the same as
%%, except that the
Natural stack is not
deleted.
In batch mode, %. causes reading of input
values for the current INPUT statement to be
terminated.
