  20     These are general inlines used to call library's functions. Macros are
  21     defined as follows:
  22
  23     LPx - function that take X arguments.
  24
  25     Modifiers (variations possible):
  26     NR - no return (void).
  27     A4, A5 - "a4" or "a5" is used as one of the arguments.
  28     UB - base will be given explicitly by user.
  29     FP - one of the parameters has type "pointer to function"
