Roberto Brambilla wanted to know how he could see get a nice indication of how a program is making progress. Theodore Gray (of Wolfram Research) showed how this can be done very nicely in Volume 7, Issue 3 of The Mathematica Journal. Using T. Gray's solution you first evaluate the line below. --------------- ShowStatus[status_] := LinkWrite[$ParentLink, SetNotebookStatusLine[FrontEnd`EvaluationNotebook[], ToString[status] ] ] ----- Now suppose i=8 and j=12. Evaluating the next two lines will cause "i=8, j=12" to show in the lower left portion of the Mathematica Window. Well that's provided the notebook you are using has a setting for the WindoeElements option to show the "StatusArea" which is done the default Style Sheet does. i=8;j=12; progress=StringJoin[ "i=", ToString[i], ", j=", ToString[j] ]; ShowStatus[progress] ----------- What Roberto Brambilla was doing is evaluating a Print statement over and over. After the program ran he had a lot of Print statements to manually delete. Evaluating the code below will delete all cells in the input notebook that were generated by Print statements. nb=InputNotebook[]; NotebookFind[nb, "Print", All, CellStyle]; NotebookDelete[nb] -------------------- Regards, Ted Ersek Down Load Mathematica tips, tricks from http://www.verbeia.com/mathematica/tips/Tricks.html
