Re: Does anything replace Recall[] ?

Hi,

there is also in version 3.0 no Recall[] command.

But $InString[$Line] will help you.
And

SetOptions[Plot, PlotLabel :> InString[$Line]]

will give you an nice boxed expression like
"\\(Plot[\\(\\(Sin[x]\\), \\({x, 0, 1}\\)\\)]\\)"

You may remove the \( \) by


SetOptions[Plot, 
  PlotLabel :> (StringReplace[InString[$Line], {"\\(" -> "", "\\)" ->
""}])]

and get the labeled result.

Hope that helps
