LIB$SYS_FAO

   The Invoke $FAO System Service to Format Output routine calls
   the $FAO system service, returning a string in the semantics
   you provide. If called with other than a fixed-length string
   for output, the length of the resultant string is limited to 256
   bytes and truncation occurs.
