DOS 4 and 5 Error Message Numbers (Copyright 1991, JP Software Inc., All Rights Reserved. Published by JP Software Inc., P.O. Box 1470, E. Arlington, MA 02174 USA, (617) 646-3975. Released June 11, 1991.) MS-DOS versions 4 and 5 include an unusual mechanism for displaying errors from external DOS commands like XCOPY, FORMAT, or DISKCOPY. These commands use the command processor to retrieve their error messages; if the messages aren't found they display cryptic messages like "Parse error 3" or "Extended error 7". 4DOS does not currently support this mechanism, but will support it in the next release, due out later this summer. In most cases these errors are generated by simple typographical errors which are almost immediately obvious. If you see error messages like this while using MS-DOS 4 or 5 with 4DOS, and the cause isn't obvious, check the list of error codes below to interpret the message. The codes listed here apply only to MS-DOS 4 and 5 external programs like FORMAT, DEBUG, and DISKCOPY. You aren't likely to see them elsewhere. Also, only common error messages are handled using this mechanism; other messages which are specific to the program in question (for example, the message "Insert source disk in drive A:", used by DISKCOPY) are embedded within the program and will be displayed correctly even if COMMAND.COM is not present. DOS 4 and 5 external programs can report either "Extended" errors or "Parse" errors. Parse errors represent problems in parsing (analyzing) the command line. The possible parse errors are: 1 Too many parameters 2 Required parameter missing 3 Invalid switch 4 Invalid keyword 6 Parameter value not in allowed range 7 Parameter value not allowed 8 Parameter value not allowed 9 Parameter format not correct 10 Invalid parameter 11 Invalid parameter combination (Parse error 5 is not used; parse errors 7 and 8 are the same.) Extended errors represent file, disk, or device access problems. These include the familiar errors like "access denied" or "file not found". The extended error codes are: Standard DOS errors: 1 Bad function 2 File not found 3 Invalid path 4 Too many open files 5 Access denied 6 Invalid handle 7 Memory destroyed 8 Out of memory 9 Bad memory block 10 Bad environment 11 Bad format 12 Invalid access code 13 Invalid data 14 Internal DOS error 15 Invalid drive 16 Can't remove current directory 17 Not same device 18 File not found 19 Disk is write protected 20 Bad disk unit 21 Drive not ready--close door 22 Bad disk command 23 Data error 24 Bad call format 25 Seek error 26 Non-DOS disk 27 Sector not found 28 Out of paper 29 Write error 30 Read error 31 General failure Network and other errors: 32 Sharing violation 33 Lock violation 34 Invalid disk change 35 FCB unavailable 36 Sharing buffer overflow 40 Not ready 41 File allocation table bad 50 Invalid net request 51 Remote computer not listening 52 Duplicate name on net 53 Net name not found 54 Net busy 55 Net device no longer exists 56 NetBIOS command limit exceeded 57 Net adapter hardware error 58 Bad response from net 59 Unexpected net error 60 Incompatible remote adapter 61 Print queue full 62 Queue not full 63 No room for print file 64 Net name was deleted 65 Access denied 66 Net device type incorrect 67 Net name not found 68 Net name limit exceeded 69 NetBIOS session limit exceeded 70 Temporarily paused 71 Net request not accepted 72 Redirection is paused 80 File exists 82 Can't make directory entry 83 Fail on INT 24 84 Too many redirections 85 Duplicate redirection 86 Invalid password 87 Invalid parameter 88 Net device fault
