  --------------------------------------------------------------------------
 
    Function 39h (MKDIR) creates a subdirectory whose path is specified in
    the ASCIIZ string at address DS:DX; the string length is limited to 64
    characters. If the function is unable to create the directory, it sets
    the Carry Flag and returns an error code in AX.
 
       Notes:         The directory name may include a drive letter.
 
                      If any of the parent directories in the path do not
                      exist, the directory is not created.
