Syntax

VOID vrq_choice( handle, start, final )
WORD handle, start;
WORD *final;

Function      vrq_choice() accepts input from the 'choice' device in
              request mode.

Opcode        30

Availability  This call is not guaranteed to be available with any driver
              and its use should therefore be restricted.

Parameters    handle specifies a valid workstation handle. start indicates
              the starting value for the choice device (1-???).
              final points to a WORD which will be filled in upon exit
              with the results of the request.

Binding       contrl[0] = 30;
              contrl[1] = 0;
              contrl[3] = 1;
              contrl[6] = handle;

              intin[0] = start;

              vdi();

              *final = intout[0];
