CX    number of records to write (if CX=0, set file's size)
DS:DX address of an opened FCB
                                                                  
Returns: AL    0 if write was successful
1 if disk full error
2 if DTA + FCB (RecSize * CX) would overrun a segment
CX    actual number of records written
                                                                  
Info: Writes multiple records to the file starting at the file address
specified by the randomRec field of the FCB.  Data is taken from
memory starting at the DTA.

Actual bytes written is (recSize * CX).

If CX = 0 on entry, the file's size is shrunk or expanded to
randomRec*recSize and no data is written.
