Using SPM
Convert uses two files: the existing backup file (the "convert from" file) and the
converted file (the "convert to" file), which is created when you run the Convert
option. The converted file contains system programming information in an
uncompressed form. The "convert from" file is unchanged. Because
uncompressed files take longer to process than compressed files, you may want
to restore this uncompressed backup to the old control unit and then create a
new backup. This new backup is in compressed form and does not have to be
converted. For more information about compressed and uncompressed files see
"Backup."
To convert system programming to Release 4.0 format, Version 4.15 of SPM is
required. This version can be easily identified by the version number, V4 , in the
upper left corner of the screen.
Help screens are available to guide you through the Convert procedure. See
"SPM Help."
Before you use the Convert option, you must complete the following tasks:
If your PC has a hard disk, install the appropriate version of the SPM
software. See "Upgrading the System."
Back up system programming. See "Backup."
Make sure you know the name of the backup file that you have created.
IMPORTANT:
-
Once the actual file conversion begins, you cannot stop the process; pressing
has no effect.
Follow the steps below to perform the conversion.
1 At the SPM Main Menu, press
2 Follow the instructions for a floppy or a hard disk.
A second window appears which displays the GOTO FLOPPY option and a
directory listing for the C:\spm\backup directory.
If the backup file is stored on a floppy disk, go to Step 3.
If the backup file is stored on a hard disk, go to Step 4.
