SHELL                                                               Menu: INFO
==============================================================================
Leaves the work session temporarily to execute operating system functions
(DOS).
(A nested command.)

Description:
This command temporarily exits the current work session in order to execute
DOS commands and subsequently returns to the original file.
There are three configurations for this command (\shel0, \shel1 and \shel2).
During the configuration process, the configuration suited to your hardware is
copied into \shell. If more than one is suitable the system will ask you to
choose an option.
Shel0 suits all graphic screens. Shel1 may be used where your configuration
includes a graphic card that allows "paging" between a graphic and
alphanumeric display. This enables an immediate redisplay of the graphic
screen when returning from \shell (shel0 has to "rebuild" the screen display,
as in the \refr command). Shel2 is used when you have a dual screen
configuration.
The graphic display is erased (if you are working with one screen) or stays
inactive (if there are two screens).

Two lines of text will appear on the active screen:
C:\directory name
Type a DOS command or press <ENTER> to end the DOS session. The first line
states the current directory. You may enter a DOS command after the `>' sign.
These two lines will appear after each DOS command.
The normal DOS prompt does not appear since you are located in a shell within
the system. To return to the graphic screen, press <ENTER>.
If you type "command" while in shell, you will enter a "true" DOS environment
where you may execute all DOS commands. To return from this environment, type
"exit".
It is recommended that you execute the \b, \save or \fcopy command before
executing this command.
NOTE:Follow the instructions listed below, otherwise unpredictable results may
occur:
1. You may use DOS commands such as DIR and COPY. More complex DOS commands
   may not work and may damage your file.
2. Do not attempt to execute any DOS disk checks, e.g., CHKDSK. These checks
   may ruin the open software files.
3. When using shel1, do not use: CLS, MODE, or any screen commands, e.g.,
   windows. Avoid using other programs that may cause screen changes.
If you changed directories while in DOS, you will automatically be returned to
the original working directory when you press <ENTER>.
