And what day is 3 days from Friday - Monday, or do you want to count 3 working days up to Tuesday? I will assume the latter. It would be something like this:

function AddWorkingDays(tdDate, tnDays)
local i, tdResult
tdResult = tdDate
for i = 1 to tnDays
  tdResult = tdResult + 1
  if dow(tdResult) = 7 && Saturday
  	tdResult = tdResult + 1
  endif
  if dow(tdResult) = 1 && Sunday
  	tdResult = tdResult + 1
  endif
next
return tdREsult

If you want to add hundreds or thousands of days, some optimizations would be convenient, for example, start dividing by seven (integer division) to see how many entire weeks you got - and multiply the number of weeks by 5 (5 working days a week).
