32: SYNTAX ERROR (long line)
The command sent is longer than 58 characters.
Use abbreviated disk commands.
33: SYNTAX ERROR (invalid file name)
Pattern matching is invalidly used in the OPEN
or SAVE command. Spell out the file name.
34: SYNTAX ERROR (no file given)
The file name was left out of the command or the
DOS does not recognize it as such. Typically,
a colon (:) has been left out of the command.
39: SYNTAX ERROR (invalid command)
This error may result if the command sent to the
command channel (secondary address 15) is
unrecognized by the DOS.
50: RECORD NOT PRESENT
Result of disk reading past the last record
through INPUT# or GET# commands. This message
will also occur after positioning to a record
beyond end-of-file in a relative file. If the
intent is to expand the file by adding the new
record (with a PRINT# command), the error
message may be ignored. INPUT# and GET#
should not be attempted after this error is detected
without first repositioning.
51: OVERFLOW IN RECORD
PRINT# statement exceeds record boundary.
Information is truncated. Since the carriage
return which is sent as a record terminator is
counted in the record size, this message will
occur if the total characters in the record
(including the final carriage return) exceeds
the defined size of the record.
52: FILE TOO LARGE
Record position within a relative file indicates
that disk overflow will result.
60: WRITE FILE OPEN
This message is generated when a write file that
has not been closed is being opened for reading.
