As an example of saving to disc, write a short program into the memory, insert a
formatted disc, then type in:
save "example"
After a few seconds, the prompt Ready will appear on the screen, and the program
will have been saved onto disc. (If not, check any error message on the screen to
establish whether you either forgot to insert your disc into the correct drive, forgot to
close the write protect hole, mistyped the command or even forgot to plug in the disc
drive(s) and switch on!).
Binary, protected and ASCII text files may be saved onto disc using the normal ,b ,p
and ,a suffixes as with cassette saving.
Disc filenames do not require the use of a preceeding exclamation mark ! to suppress
reading/writing prompts and software messages on the screen. Any preceeding ! will
be removed from the filename and ignored by AMSDOS.
Catalog
Like cassettes, discs can be catalogued, but at much greater speed. After saving the
above program, type in:
cat
On the screen you will see:
Drive A: user 0
EXAMPLE.BAS
1K
The filename will be displayed, including any specified or token second field. together
with the file length (to the nearest higher kbyte).
Loading From Disc
Programs may be loaded from disc then run, using the commands:
load "filename"
run
or they may be run directly using the command:
run "filename"
Note that protected programs may be run directly only.
If you are operating 2 disc drives, you may specify which Drive (A or B), that you
require a function to be performed on, by issuing the command |a or |b before the
save, cat, load or run instructions.
