If a Y is entered, the entire program area of memory will be used
for the file duplication process. This will speed the duplication
process. However, by allowing the program area to be used for
duplication, the contents of MEM.SAV cannot be rewritten into
RAM. Any BASIC program that you intended to save using
MEM.SAV
will be lost when the system returns to BASIC.
Any response other than Y disallows the use of the program area
of memory for the Duplicate File operation. This allows the
contents of MEM.SAV to be later rewritten into RAM . However,
by disallowing the us e of the program area of memory, the time
necessary to duplicate the file will increase.
Be extremely careful when using the Duplicate File operation
with DOS 1.0. When this operation is specified in DOS 1. 0, the
program area of memory will be erased. Any existing files will be
lost after the duplication process has been completed.
An example of the u se of the Duplicate File option is given in
Illustration 7-18. Notice that the diskettes may have to be
swapped several times in order to complete the duplication
process.
USING BASIC PROGRAMS ON DISKETTE
In the following sections, we will discuss the BASIC statements
used
to save programs on diskette and then reload these
programs back
into memory.
Saving BASIC Programs On Diskette
Once a BASIC program ha s been entered into RAM via the
keyboard, it must be stored on diskette or it will be lost when the
Atari's
power is turn ed off or when a NEW statement is executed.
The
SAVE and LIST statements are used to save a BASIC program
on diskette.
The
SAVE statement uses the followng configuration when used
with the Atari 810 Disk Drive.
