Int 21 Fn 86  - European MS-dos 4.0 - "setfiletable" - Install New File H  [D]

   AH = 86h
   BX = total number of file handles in new table

Return: CF clear if successful
   CF set on error
       AX = error code (06h,08h) (see AH=59h)
Desc:  adjust the size of the per-process open file table, thus raising or
     lowering the limit on the number of files the caller can open
     simultaneously

Notes: any currently-open files are copied to the new table
   if the table is increased beyond the default 20 handles, only the
     first 20 will be inherited by child processes
   error 06h is returned if the requested number of handles exceeds
     system limits or would require closing currently-open files
