SAVE
Abbreviation: S <SHIFT+A>
TYPE: Command
FORMAT: SAVE ["<file-name>"][,<device-number>][,<address>]
Action: The SAVE command is used to store the program that is
currently in memory onto a tape or diskette file. The program
being SAVED is only affected by the command while the SAVE is
happening. The program remains in the current computer memory
even after the SAVE operation is completed until you put something
else there by using another command. The file type will be "prg"
(program). If the <device-number> is left out, then the
C64 will automatically assume that you want the program saved
on cassette, device number 1. If the <device-number> is
an <8>, then the program is written onto disk. The SAVE
statement can be used be used in your programs and execution will
continue with the next statement after the SAVE is completed.
Programs on tape are automatically stored twice, so that your
Commodore 64 can check for errors when LOADing the program back
in. When saving programs to tape, the <file-name> and secondary
<address> are optional. But following a SAVE with a program
name in quotes ("") or by a string variable (---$) helps
your Commodore 64 find each program more easily. If the file-name
is left out it can NOT be LOADed by name later on.
A secondary address of I will tell the KERNAL to LOAD the tape
at a later time, with the program currently in memory instead
of the normal 2048 location. A secondary address of 2 will cause
an end-of-tape marker to follow the program. A secondary address
of 3 combines both functions.
When saving programs onto a disk, the <file-name> must
be present.
EXAMPLES of SAVE Command.
| SAVE |
(Write to tape without a name) |
| SAVE"ALPHA",1 |
(Store on tape as file-name "alpha") |
| SAVE"ALPHA",1,2 |
(Store "alpha" with end-of-tape
marker) |
| SAVE"FUN.DISK",8 |
(SAVES on disk (device 8 is the disk)) |
| SAVE A$ |
(Store on tape with the name A$) |
| 10 SAVE"HI" |
(SAVEs program and then move to next program
line) |
| SAVE"ME",1,3 |
(Stores at same memory location and puts an end-of-tope
marker on)
