Copy VIC Disk Files

Roger L. Smith, Mesa, AZ

The "Copy 2031 Files" program by G. H. Watson (COMPUTE!, August 1982) was greatly appreciated. It was suggested that the program might run on the VIC-20 if appropriate changes were made. The following program makes those changes.

The program will work with either VIC-1540 or the new VIC-1541 disk drives. However, your VIC must have a 3K memory expansion plugged in since the program uses memory beginning at the expansion start-of-BASIC address ($0400) to handle the file transfer.

As noted in the original article, the program will handle BASIC program files. To copy sequential files (data files, ASM/TED files), replace the appended P with an S by using POKE 7672,83. Program files use POKE 7672,80. If you want to transfer more than one file, you will have to type SYS 7354 each time.
