Rexx can't call vio functions directly.

Cset++ (are you really using the old c set/2?) should be able to call Vio
functions without any problem.  If you are having a linking problem,it is
probably because have not prototyped them correctly (are you compiling with
warnings enabled?  You shoud always compile with AT LEAST "icc
/Kb").

Here's a program that works:


 // compiled with ibm cset++ v2:
 // icc /W2 /Wall /O /Oi /Rn /Sse /G4  vio.c
 #define INCL_NOPMAPI
 #define INCL_VIO
 #include 
 #include 
 #include 

 int main(void)
 {
     int i;
     char msg[40];
     BYTE attr;

     VioScrollUp(0, 0, 0xffff, 0xffff, 0xffff, " \x7", 0);  // cls

     attr = 15;  // start off with bold on black background.
     for(i=0; i<22; i++){
         sprintf(msg, "Line %2d: Programming is fun!", i);
         VioWrtCharStrAtt(msg, strlen(msg), i, i, &attr, 0);

         attr += 16;     // change background colour.  Note: attributes
                         // are just like they are under dos when poking
                         // into video memory.
     }


     VioSetCurPos(23, 0, 0);      // so cursor is at bottom when program ends
     return 0;
 }
