Hi all, 

sometimes trying to write FD help makes me crazy. 

Mode is a typical example. At

there is a big explanation what the original mode.com from 1995 can do
for me. But the last change was in 2015 - and as it looks like a lot of
things were changed without a documentation, among others FD has no park

If I understand this right, the actual errorlevels should be like this
(found them at modecp.c - hopefully correct?)

MODE has the following ERRORLEVEL / EXITCODES [1]:
    100:  INTERNAL ERROR: size for prepared table too small
    101:  No compatible FreeDOS DISPLAY [2] driver loaded.
          Syntax example: ... DISPLAY [2] CON=(VGA,437,1)
    102:  File not found
    103:  Error specifying codepage / buffer
    104:  Error: selected buffer not present
    105:  Syntax error
  check codepage:
    26:  Active codepage was never set
    27:  Device read codepage error
  prepare codepage:
    27:  Codepage was not found in CPI file
    29:  Could not get codepage info from file (or XMS troubles)
    31:  specified CPI file is damaged (or XMS troubles)
  end prepare codepage:
    31:  INTERNAL ERROR: End prepare without Begin prepare
  select codepage:
    26:  Specified codepage was not found in file
    27:  KEYB failed to change codepage
    29:  Device select codepage failed (or XMS troubles)
    31:  Device select codepage error

(I think 0 should be added too)

The orignal looks as follows:

Errorlevels returned by MODE are as follows:

    0    No error
    115    Serial port does not exist (either for COMn: or LPTn:=COMx)
    117    No hard disk(s) found to park
    118    Specified video mode is not supported on this machine
    162    Insufficient memory (MODE requires about 6K of memory)
    241    Parameter out of range (e.g. time value, LPT port number etc)
    242    Cannot have 43-line or 50-line modes with modes other than
    243    Unknown baud rate
    244    Must specify both DELAY= and RATE= for typematic setting
    246    More than one command or command type was given
    255    Incorrect usage syntax (all usage syntax errors)

Question: Which are the correct errorlevels?
