Anyone want a rudimentary printF function in Lingo? If you don"t then please delete this message. If you do, then this is the limit of the function. It only pads spaces after the last character, not before or after the decimal point. How do you call it? You call it like this: PrintF [[a,b], [c,d],...] or printF [[a,b]]. Ex: PrintF [[x,20],["-",1],[y,20]]. This will reserve 20 characters for x, add a seperating "-" sign and then reserve 20 characters for y. You have an virtually unlimited number of arguments you can pass in one PrintF.

  set the floatprecision = 20
  set mylist =  ["Sin(x)",2, 10, .1]
  set thestart = getat(myList, 2)
  set theEnd = getat(myList, 3)
  set theStep = getat(myList, 4)
  set theFn = getat(myList, 1)
  set theLoop = theStart
  put "Evaluating "& string(theFn)& " from "&theStart&" to "&theEnd&", step "&theStep
  repeat while theLoop <= theEnd + theStep
    set x = theLoop
    PrintF [[x, 20], [" -> ",4],[ value(theFN), 22]]
    set theLoop = theLoop + theStep
  end repeat
end

on PrintF argumentList, returnField

  set output = Empty
  repeat with currentArg =1 to count (argumentlist)
    set DesiredLength = getat(getat(argumentList,currentarg ), 2)
    set realLength = the number of chars in(string(getat(getat(argumentList,currentarg ), 1)))
    put getat(getat(argumentList,currentarg ), 1) after output
    -- here we fill in the spaces after the statements have been output
    set output = (FillInTheSpaces(realLength, DesiredLength, output))
  end repeat
  put output
end

on FillInTheSpaces realLength, DesiredLength, output
  repeat with temp = realLength to DesiredLength
    put " " after Output
  end repeat
  return output
end
