Mary Beth, One way to do this is to add the function definition to your init.m file , the location of which depends on your OS. On Windows XP with Mathematica 5.0.1 for Students, I opened up C:\Program Files\Wolfram Research\Mathematica\5.0\Configuration\Kernel\init.m with any decent text editor and appended the line marybethEG[x_]:=x+1 to the file. The kernel automatically loads the contents of that file so you can do In:= marybethEG Out= 8 -- Curt Fischer
