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.
%% 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 synchronization of the
input files in the case of an error.

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.
