Invalid command for device, or invalid command
sequence for device.
Hardware error, or tape cannot be correctly
positioned.
Hardware error, unmarked tape, lack of power
on the second tape, erased or magnetically
dam~ged
tape, or movement of tape beyond
end of marked tape.
Tape cartridge not inserted.
Tape is file-protected.
Recovery
Enter GO END to end the program. Check OPEN and
CLOSE statements for valid device addresses. Valid device
addresses are 500, ESO, or E40. The error can also be caused
by attempting to open or CHAIN to file 0, for example: OPEN
FL1, 'ESO', 0, OUT. File values such as.5 can also cause the
error. If OPEN or CHAIN statements were incorrect, correct
them and run the program again. If the OPEN and CHAIN
statements are correct, retry the operation. If the error persists,
call the service personnel.
If running a BASIC program, enter GO END to end the pro-
gram and then retry the operation causing the error. If the
error occurs on a LOAD or SAVE command, retry the
command. If the error persists, call the service personnel.
If the error occurs due to uneven winding of the tape, the tape
should be moved to its extremes as described under Tape
Cartridge Handling and Care. If the error occurs during an
operation, retry. If the error occurs while attempting a com-
mand or opening a file, rewind and retry. If the retry does
not work in either case, call the service personnel.
If the error occurs during execution of a BASIC program, enter
GO END to end the program. Then rewind the tape and retry
the operation causing the error. If the error occurs on a LOAD
or SAVE command, retry the command. If the error recurs,
issue the REWIND command (after issuing GO END, if required) , ./
and retry the operation. If the error recurs, call the service
personnel.
Insert tape cartridge. If the error occurs on a command oper-
ation, reenter the command. If the error occurs during pro-
gram execution:
Insert tape cartridge and enter GO END to end the program.
- Insert tape cartridge and enter GO x to continue, where x
is the statement number of the OPEN statement.
If the error recurs, call the service personnel.
If you want to write to tape, turn the SAFE switch on the
cartridge off of the safe position and:
1. If the error occurs on a command operation, reenter the
command.
2. If the error occurs when opening a file during program
execution:
Enter GO END to end the program.
Enter GO x to continue, where x is the statement
number of the OPEN statement.
If the error still recurs, call the service personnel.
