.L cjjFit.C
TF1* cjjFit = new TF1("cjjFit",cjjFit,-1,1,4);
cjjFit->SetParameters(0,1,1,1);
cjjFit->Draw();
This works. I then decide to edit cjjFit.C to change the function.
But when I type
delete cjjFit;
.U cjjFit.C
I get a message saying 
Error: G__unloadfile() File "cjjFit.C" not loaded  FILE: LINE:0
I now edit the file and save it. Then I type
.L cjjFit.C
TF1* cjjFit = new TF1("cjjFit",cjjFit,-1,1,4);
cjjFit->SetParameters(0,1,1,1);
cjjFit->Draw();
The draw fails. The function is simply a line at y=0. Note this occurs 
even if I do not edit the file.
Any ideas? Thanks,
Chris
