: I'd like to propose this addition to the runtime system -- a VOID typedef, : so that from RTL, I can use the "VOID" mode for c-calls and such. VOID c-calls are already widely used. Where have you seen the type referenced as "VOID" in generated code? Where I did this: (c-call VOID "my_func") Unless I stipulate the mode, the default mode for c-call is DFLT. Ben
