ABORT

Purpose:    Sets the emergency program exit option activated by the
            [SysReq] key.

Syntax:     ABORT = <ON|OFF>

By default: ABORT=ON

Note:

     In certain cases when a program halts, it is sufficient to take
measures on exiting the current process in order to resume normal system
operation. If the ABORT is ON, you may do the above by pressing [SysReq].
Nevertheless, such exiting is not always correct as the program could have
allocated some part of extended and/or expanded memory, and DOS can not
release it automatically, or temporary files may have been created which can
be deleted just on normal completion of the program.  Besides that, the
aborted program could have made changes to the interrupt vectors table,
making further operation impossible.
