;* search - Search record structure
;
; This strucure defines the result buffer format for search returns
; for int21h based file searches: 11H/12H FCB Find First/Next
;	and 4eH/4fH path based Find First/Next
;
; There are two areas in the search_record reserved for use by file system
; drivers. One is to be used by local file systems such as FAT or CDROM
; and the other is to be used by network file systems such as an SMB or
; NCP client. The reason for the split is because many network file
; systems send and receive the search key directly on the net.
