Option 3. Disp EC Ver.
The Disp EC Ver. option is primarily for your service representative's use. This
option will display a 4-digit code for each interpreter module. The first two digits
are
the module identification and the next two digits are the EC version.
The EC Version program will issue prompting messages and wait for the user to
respond to each message.
Option,4. Key-Enter IMF
This option allows the service representative to enter IMFs from the keyboard. The
IMF is then written to file 2 on the tape containing the IMFs. The IMF can then be
loaded
or copied from the tape.
Option 5. End of Job
This option causes the APL language to be available again.
Option 6. Tape Recovery
The Tape Recovery option allows the user to recover data from a file or files on
which
tape read errors (ERROR 007 ddd) are occurring. The Tape Recovery Pro-
gram
can be used on the following files:
• Exchange (file
type 01)
• General exchange (file
type 02)
• BASIC source (file
type 03)
• APL internal
data format (file type 08)
The Tape Recovery program will issue prompting messages and wait for the user to
respond to each message.
The Tape Recovery program will recover as much data as possible in the file; some of
the data in the record where the tape read errors occur is not recoverable; some of
the data that precedes and follows that record may also not be recoverable.
