34:
SYNTAX ERROR (no file given)
The file name was left out of a command or the DOS does not recognize it as such.
Typically. a colon (:) has been omitted. Try again.
39:
SYNTAX ERROR (invalid command)
The DOS does not recognize a command sent to the command channel (secondary
address 15). Check your typing and try again.
50:
RECORD NOT PRESENT
The requested record number has not been created yet. This is not an error in a new
relative file or one that is being intentionally expanded.
It
results from reading past
the last existing rccord. or positioning to a non-existent record number with the
Record# command.
51:
OVERFLOW
IN
RECORD
The data to be written in the current record exceeds the record size. The excess has
been truncated (cut off). Be sure to include all special characters (such as carriage
returns) in calculating record sizes.
52:
FILE TOO LARGE
There isn't room left on the diskette to create the requested relative record. To
avoid this error, create the last record number that will be needed as you first create
the file. If the file is unavoidably too large for the diskette, either split it into two
files on two diskettes, or use abbreviations in the data to allow shorter records.
60:
WRITE FILE OPEN
A write file that has not been closed is being re-opened for reading. This file must
be immediately rescued. as described in Housekeeping Hint #2 in Chapter 4. or it
will become a splat (improperly closed) tile and probably be lost.
61:
FILE NOT OPEN
A file is being accessed that has not been opened by the DOS. In some such cases
no error message is generated. Rather the request is simply ignored.
62:
FILE NOT FOUND
The requested file does not exist on the indicated drive. Check your spelling and try
again.
63:
FILE EXISTS
A file with the same name as has been requested for a new file already exists on the
diskette. Duplicate file names are not allowed. Select another name.
64:
FILE TYPE MISMATCH
The requested file access is not possible using files of the type named. Reread the
chapter covering that file type.
