Introduction to BASIC-80 BASIC-80

Loading a Program

The LOAD command loads a BASIC-SO program from disk. The program can be stored in either ASCII or internal format. To load a program named ANLYZE from a disk in drive 1:

LOAD ":F1 :ANLYZE"

OK

You can now run, list, or edit the program.

Saving a Program

The SAVE command copies your program from Intellec memory to disk. You must specify a filename, enclosed in quotation marks:

SAVE ":F1 :ANLYZ"

The SAVE command can also be used to list the contents of the current file on a line printer or other output device. For example, to list the current file on a line printer, you would enter:

SAVE ":LP:" ,A

4"4;0"1"

You can only write data to one disk in any disk drive each time you invoke BASIC. If you write to a disk in a given drive, remove that disk and insert another, and try to write to the new disk, you lose all data on the new disk. The exception to this is on systems with more than one drive. It is permissi- ble to change a disk on a drive if that drive has not been written to since another drive has been written to. As an example, if your BASIC-SO pro- gram writes on a file in drive 0, and you then remove that disk, insert another and write on it, the contents of that second disk will be lost. If, however, your program wrote on a disk in drive 1 between writing on the different disks in drive 0, there would be no problem.

There are no restrictions on reading from disks.
