VBForm functions in Vantage 8.x

How do I use the old Vantage 6.x VBForm commands "RUNPROG" and "RUNVBP" with Vantage 8.x?
I can create the button in Vantage 8.x but I receive an Error. BC30451 - line 65 (157) - Name "RUNPROG" is not declared when trying to add the code from my Vantage 6.x VBForms to it.
