110 END

The program is intended to accept up to 80 lines of text (120 chars long) and write them to records in the OUTPUT data file on disk.

When run, the program creates the data file, and continues to run, but no data is displayed; the program seems to run 'forever' requiring RESET to regain control. Further testing showed it basically hangs forever on the initial ENTER command.

I suspect DOSLINK sent the first line of the test file, and the program is waiting for the rest of the 120 bytes in the first record. Fixed length records may be required here.

Well, it's surprising. ENTER is an I/O statement commonly used to get ASCII CR-LF terminated data from instruments, and I expect it to work with DOSLINK on series 80 as it does on series 70.
Are you sure the DOSLINK "in file" is correctly set to an non-empty text file in ILPer?
