Function 10h Close File (FCB)

Closes a File After a File Write

entry AH 10h

DS:DX pointer to an opened FCB

return AL 00h if the file is found and closed

0FFh if the file is not found in the current directory

note 1) This function call must be done on open files that are no longer needed,

and after file writes to insure all directory information is updated.

2) If the file is not found in its correct position in the current

directory, it is assumed that the diskette was changed and AL returns

0FFh. This error return is reportedly not completely reliable with DOS

version 2.x.

3) If found, the directory is updated to reflect the status in the FCB, the

buffers to that file are flushed, and AL returns 00h.
