Description

   When translated code support is requested, the compiled code
   must call the special service routine, OTS$CALL_PROC. The actual
   parameters to the target function are passed to OTS$CALL_PROC as
   though the target routine is native code that is being invoked
   directly.

   OTS$CALL_PROC first determines whether the target routine is part
   of a translated image.

   If the target is in native code, then OTS$CALL_PROC completes
   the call in a way that makes its mediation transparent (that is,
   control need not pass back through it for the return). The native
   parameters are used without modification.

   If the target is in translated code, then OTS$CALL_PROC passes
   control to the Translated Image Environment (TIE).
