Using DOS Commands in LOVE-83Forth
==================================
L.O.V.E. Forth can invoke the MSDOS command interpreter to perform
tasks such as deleting files, copying files or displaying the contents
of a directory, with a simple and flexible DOS command. The DOS command
is a Forth word in the TOOLBOX vocabulary
To use the DOS command interactively just type:
DOS
followed by the MSDOS command that is desired and press the
<return> key.
Example:
DOS dir/w <cr>
will display the contents of the current directory and then
return to Forth.
DOS commands can be embedded in source code screens or in text
files with the restriction that there be no other Forth words on that
line after the actual MSDOS command appears. The reason for this is
that L.O.V.E. Forth passes all the information after the word DOS up to
the carriage return character if interpreting from the keyboard or a
text file, or up to the end of a screen line if interpreting from a
block. Any Forth words on the rest of that line will confuse the MSDOS
command interpreter.
If a programmer desires to remain in the shell of the command interpreter
for an extended period the DOS command can be used to invoke a new shell
by stating:
DOS <cr>
The MSDOS prompt will appear on the display.
To return to Forth the word "exit" must be typed to exit from the
shell.
