                                                         Compatibility: 2.0+

 Returns: AX    error code if CF is set to CY

    Info: Deletes an existing file.

    DS:DX points to an ASCIIZ string in the form...
             d:\path\filename.ext◄0►
          ...which identifies the location and name of the file to delete.
          It cannot contain wildcards▲.  If drive and/or path are omitted,
          defaults are assumed.

          If CF is set on return, an error code is in AX and no action was
          taken.

   Notes: ■ This function removes the file's directory entry from the
            directory (actually, it overwrites the first byte of the file
            name with 0e5H) and updates the FAT to deallocate its disk
            space.  It does not physically erase the file's data.

          ■ If Undelete's Delete Sentry is active, it will intercept this
            call and move the file's directory entry into the \SENTRY
            directory, giving it a unique name and recording the
            transaction in CONTROL.FIL.  The file will actually be deleted
            when the disk space is needed.

          ■ This function will not delete files having the read-only
            file attribute.  You may use fn 4301H (change file attribute)
            to clear this attribute.
