If you want to execute an MS-DOS command, pressing
C causes LFM to prompt at the bottom of the screen
DOS Command: [ ]
where you can type any MS-DOS command and press
Enter to execute.
F9 Go Key
Pressing F9 at the LFM main menu causes LFM to load and
execute programs based on the file’s extension. For
example, if you want to execute the
MS-DOS EDIT utility on a
particular file, move the highlight to the EDIT.COM line
under the DOS directory listing and press F9. Depending on
how you have set up your LFM Execute Commands item in
the F10 LFM Setup Commands menu, LFM may prompt you
at the bottom of the screen
Press ESC to cancel, any other key to execute:
Press any key except ESC. Depending on how you have set
up your F10
LFM Setup Commands menu, LFM then may
prompt:
Parameters: [ ]
At this prompt you can type the pathname of the file you
want to edit and press ENTER (or, if you are executing
another type of file that requires no parameters, press
ENTER to start execution). In the example, the
MS-DOS EDIT
screen would appear.
When you exit the executable program, LFM reloads and
displays its main menu.
LFM uses extended/expanded memory for itself when you
use the Go function, reserving all but about 8 KB for the
program. If no extended/expanded memory is available,
LFM uses about 130 KB of standard base memory.
