DOS Error Messages 403
34 SYNTAX ERROR (file name missing)
DOS did not receive a necessary file name. The file name could be present
but not recognizable (e.g., necessary separating punctuation is missing).
39 SYNTAX ERROR (command not valid)
A command sent to the DOS through the command channel was not
recognized by DOS.
50 RECORD NOT PRESENT
This error is the result of attempting to access a record beyond the end of a
relative file. During addition of a new record, this message is expected and
can be ignored. Reposition the pointer before attempting a GET or INPUT.
51 OVERFLOW IN RECORD
The information sent to a relative file record in a PRINT# command
exceeded the record length in the file. The information is truncated. It
should be noted that a carriage return character sent as a record terminator
counts as a byte in the record.
52 FILE TOO LARGE
Creating the record number in the current Position command in a relative
file will cause a disk overflow.
60 WRITE FILE OPEN
Read access was requested for a write file that was not closed.
61 FILE NOT OPEN
An attempt was made to access a file that was never opened.
62 FILE NOT FOUND
A file was requested that does not exist on the diskette.
63 FILE EXISTS
The file name designated for a file being created already appears on the
diskette.
