If VChooseFrom is literally a list of sequential numbers starting at 1, as
noted above, then you could use this function where maxNum is the number of
lines in VChooseFrom.

function getrndlines maxNum, VNumToChoose
  repeat until the number of lines of temp = VNumToChoose
    put random(maxNum) into thisNum
    if thisNum is not among the lines of temp then put thisNum & return
after temp
  end repeat
  delete the last char of temp
  return temp
end getrndlines

You could save RAM by making VChooseFrom simply maxNum. That is to say, if
VChooseFrom is 1 through 125, why not just say VChooseFrom = 125?
