Using the Change Directory Function
Most of the time, you won’t need to use the Change Directory function. The Change
Directory function is normally used to change the default directory for Load and Save file
commands. This is useful if you repeatedly need to load or save from a diskette, or if you
need to repeatedly load or save from a directory that you didn’t start running MICRO from.
Even if you don’t use the Change Directory function, you can still load and save from
other directories. You will need to type in the entire path name for the file.
For example, if you have “changed directories” to C:\MISC\OTHER\STUFF, when you
save a file, the typed filename would be:
TESTFILE.PLC
If you have not changed directories, the typed filename would be:
C:\MISC\OTHER\STUFF\TESTFILE.PLC
The MICRO.CFG File
Whenever you Save configuration in the Setup menu, a MICRO.CFG file is written to
the current directory. If you are in the \MICRO directory, MICRO.CFG is written there. If
you are in another directory, then MICRO.CFG is written there instead. You can have as
many MICRO.CFG files as you want, but each must be in a separate directory.
The MICRO.CFG file contains information about the video characteristics of your
computer and your serial port. It also contains the format of your online data displays.
This file is manually loaded from the current directory when you use the Restore
function from the Setup menu. It is automatically loaded when you start up the
programming software from a directory which has a resident MICRO.CFG file.
Hints for a Basic Application
If you will not be creating a large number of programs, or if you don’t want to use
directories, start up the software by entering:
C:>CD \MICRO
C:\MICRO>MICRO
When you start the software in this way, the MICRO.CFG file (configuration file) that is
already saved in the \MICRO directory is used to set the video mode, serial port
selection, and online data display format. You can change the format at any time, then
Save the new format.
When in the Disk menu, you can use Load and Save to the present directory (\MICRO),
and not need to change directories. If you want to save a file to diskette or load a file
from diskette, enter the diskette drive name as part of the filename. For example:
A:1STPROG.PLC
