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 or 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 to
the record size, this message will occur if the total characters in the
record (including the final carriage return) exceeds the defined size.
52: FILE TOO LARGE
Record position within a relative indicates that disk overflow will result.
60: WRITE FILE OPEN
This message is generated within a write file that has not been closed is
being opened for reading.
61: FILE NOT OPEN
This message is generated when a file is being accessed that has not been
opened in the DOS. Sometimes, in this case, a message is not generated;
the request is simply ignored.
62: FILE NOT FOUND
The requested file does not exist on the indicated drive.
63: FILE EXISTS
The file name of the file being created already exists on the diskette.
64: FILE TYPE MISMATCH
The file type does not match the file type in the directory entry for the
requested file.
65: NO BLOCK
This message occurs in conjunction with the B-A command. It indicates
that the block to the allocated has been previously allocated. The parame-
ters indicate the track and sector available with the next highest number.
If the parameters are zero (0), then all blocks higher in number are in use.
