Copying relative files is next to impossible with conventional file copiers. Copy Rel 64, a machine language program that loads and runs like a Basic program, solves that problem. Copy Rel 64 can copy up to the maximum 65,535 records in a relative file. It's simple to use, and is compatible with the 1541, 1571 and 1581 disk drives.
Begin by backing up COPY REL.HEX and COPY REL.ML using the Copy command from Menu 64. To use the program, run COPY REL.ML from either the work disk or Menu 64, insert a disk with the relative file to be copied, and type in the name of the file. If you want to see the directory, hold down the F3 key; press RUN/STOP to halt the directory.
Copy Rel 64 will scan the file parameters, then prompt you to place the destination disk in the drive. Once this is done, it will create the file on the destination disk.
After the file has been created, you are prompted to reinsert the source disk and press return. Copy Rel 64 will copy each record into the computer's memory (in addresses $2800 to $FFFF) then, when memory is full, it will tell you to reinsert the destination disk.
You will be able to see your record data displayed during the reading and writing operations. Follow each disk swap prompt as instructed for a perfect copy of your relative file.
