Function 4Eh (78)        Find First Matching File (FIND FIRST)
 
    Finds the first filename matching the specified filespec, and provides
    information at the current Disk Transfer Address (DTA).
 
       On entry:      AH         4Eh
                      CX         File attribute
                      DS:DX      Pointer to filespec (ASCIIZ string)
 
       Returns:       AX         Error code, if CF is set
 
       Error codes:   2          File not found
                      3          Path not found
                      18         No more files to be found
 
                      Call Function 59h for extended error code information
                      (DOS 3.0 and above).
 
  --------------------------------------------------------------------------
 
    This function searches for the first filename matching the filespec
    (ASCIIZ string pointed to by DS:DX). The filespec may include a drive
    letter and path, and the filename can include wildcard characters.
 
    The function returns information in a 43-byte area at the current DTA.
    The information is formatted as follows:
 
           Offset     Size       Description
            00h        21        Used by DOS for find-next processing
                                 (Function 4Fh)
            15h         1        Attribute of file found
            16h         2        Time stamp of file
            18h         2        Date stamp of file
            1Ah         4        File size in bytes
            1Eh        13        Filename and extension, as an ASCIIZ string
 
    The filename and extension are reported in conventional notation, with
    blanks removed and a period between the filename and the extension. If
    the file has no extension, the period is suppressed.
 
       Notes:         You can search for the next matching file using
                      function 4Fh (Find Next Matching File).
 
                      Function 1Ah can be used to set the DTA (Disk
                      Transfer Address).
 
                      You can control the scope of the search by entering
                      an attribute byte in CX. If CX is 0, the function
                      searches for normal files only. If CX specifies any
                      combination of the hidden, system, or directory
                      attribute bits, the search matches normal files and
                      also any files with those attributes. If CX
                      specifies the volume label attribute, the function
                      looks only for entries with the volume label
                      attribute. The archive and read-only attribute bits
                      have no effect on the search operation.
