Well done ChemE.
Either Vpp or Vpp40 will go to +13V depends on the selection of the PIC type. Vpp40 is for the 40-pin and Vpp for the rest.
To test its function, just selects 16F628 inside WinPicProg and it will turn on Vpp instead of Vpp40 while doing a READ operation.
+13V is required to read or write to the PIC. Therefore either Vpp or Vpp40 will turn on so their original label are misleading.
