Commodore 1541-II - Saving Programs

Note: the "0:" at the start of file names is a holdover from the days when all
Commodore disks had two drives in the same cabinet. Although the 1541 will
normally default to drive 0 (not having a drive 1,) it is best to specify the drive
number whenever saving or writing a file. This avoids potential confusion in DOS
(the Disk Operating System.)
SAVING PROGRAMS: BASIC 3.5
Before you can save a program to diskette, the diskette must be formatted, as
described earlier. Saving to diskette is just like saving to cassette, except that the device
number of the disk drive is not optional.
FORMAT FOR THE DSAVE COMMAND
DSAVE "file name",Ddrive #,Udevice #
where "file name" is any string expression of up to 16 characters, optionally followed by
the drive number (the "D" parameter, always 0 on the 1541), and the device number of
the disk drive (the "U" parameter). If omitted, the drive number defaults to 0, and the
device number to 8.
However, it will not work in copying programs that are not in the Basic text area,
such as "DOS 5.1" for the Commodore 64. To copy it and similar machine language
programs, you will need the .S command of the machine language monitor built into the
Commodore 16 and Plus/4. To access a built-in monitor, type MONITOR. To exit-a
monitor, type X alone on a line.
FORMAT FOR A MONITOR SAVE
S''drive #:file name",device #,starting address,ending address■+ 1
where "drive #:" is the drive number, 0 on the 1541; "file name" is any valid file name
up to 14 characters long (leaving 2 for the drive number and colon); "device #" is a two
digit device number, normally 08 on the 1541 (the leading 0 is required); and the
addresses to be saved are given in Hexadecimal (base 16,) but without a leading dollar
sign ($). Note that the ending address listed must be 1 location beyond the last location to
be saved.
EXAMPLE:
Here is the required syntax to save a copy of "DOS 5.1"
