Loading a BASIC Program from Disk
Before a floppy disk can be used with BASIC, it must be mounted. Type “MOUNT
0” to tell BASIC to mount the floppy that is in drive zero. After the command
completes (it may take ten or more seconds to complete), type “FILES” to list
the files present on the disk.
You can load a program with the “LOAD” command, or load and run a program
with the “RUN” command. The file name specified for either command must be
contained in quotes and is case-sensitive. For example, to load the StarTrek
game, type the following:
LOAD “STARTREK”
and press RETURN. After the program loads, you can type “LIST” to look at the
program or “RUN” to execute the program.
Loading a BASIC Program through the Console
You can also load a BASIC program through the console in the same manner as
detailed in the 4K BASIC and 8K BASIC demonstrations. This allows you to load
new programs from a PC and then save the program to the floppy disk.
The “SAVE” command writes a program in memory to the floppy disk. For exam-
ple, to save a program in memory to the file name “NEWPROG,” type the follow-
ing:
SAVE “NEWPROG”
and press RETURN to write the program to the floppy disk.
If you have modified a floppy with new content and you want to archive the
floppy to your PC, follow the “Save Floppy Content to PC” instructions in the
“Floppy Disk Menu” section of Part 2, “Configuration Monitor” to write the
floppy image to a file on your PC.
