00279: Reading or writing to tape via BBx or PRO/5


Reading or writing to tape via BBx or PRO/5


Handling tape drives is specific to each device and how the operating system treats them. A “no-rewind” type of tape drive should be used. Otherwise, if the device doesn’t receive a steady stream of data from the program, it might decide to rewind itself while the program is busy doing other things, and thus would overwrite previously written data the next time a write is performed. 

In the CONFIG.BBX, specify the tape drive as a printer by beginning the bbxname with an “L” or a “P”. Open the device in the program, then perform WRITE RECORDs to output the data just as though it was being printed to a printer. 

When reading a tape, it is not necessary to use an alias. Just open the device and use READ RECORDs to read the data.
