                   INT 21,67 - Set Handle Count  (DOS 3.3+)

       AH = 67h
       BX = new maximum open handles allowed

       on return
       CF = 0 if successful
          = 1 if error
       AX = error code if CF is set  (see DOS ERROR CODES)

       - gives program control of the number of files simultaneously open
       - if CX is less than the current number of open files the change
         will take effect when the number of open handles falls below
         the new limit
       - this function allows the application to use more than 20 files,
         up to the FILES=N limit
       - earlier copies of IBM DOS 3.3 sometimes incorrectly allocates
         memory (up to 64K) if an even number of handles is requested
       - only the first 20 files handles are copied to a child process
         regardless of the max number of files
       - it is possible to allocate more than 255 file handles but it is
         difficult to use more than 255

       - see  SFT   FILE HANDLES
