Even when you check inside the PRFILE or FIFILE with Text or Hex Editor, its impossible to know which line represents what.
So, you must use the conversion as used in the macro, PRFCNVGX Conversion.
Alternatively, just load the PRFILE & FIFILE into the BSC out of hours, and modify the parameters using a premade basic excel script. I dont this before, it takes 10 minutes to make excel to output all the commands and then just 2 minutes to throw the commands in.
You could then extract the PRFILE & FIFILE and copy them to another BSC.
