The following list contains all the 5100 error codes. Any detected error will deac-
tivate keys on the keyboard and cause the display screen to flash. To stop the
flashing display, press ATTN. Error codes below 100 are I/O errors and are dis-
played as 3-digit numbers, followed by three blanks and one of the following de-
vice addresses: 500 for the printer, E80 for the built-in tape unit, or E40 for the
auxiliary tape unit. Error code 800 is for UTI L MODE COM when the device is not
attached. Refer to
Serial If 0 Adapter
for other valid device addresses. Error codes
above 100 are simply displayed as 3-digit numbers. Unless otherwise specified, you
can recover from each execution error with one of the following procedures labeled

Note that if errors are detected during execution of a program involving tape

these commands can cause incorrect operation when the program is restarted.
If I/O errors (01-99) occur on a tape file, the file is automatically marked not open
and cannot be accessed by GET or PUT statements. An output file has not been
properly closed and may not be accessible. GO END closes all other files.
