I've got 25 options the user can take from 5 different choices.

I've tried using the "switch" function, but the "case" test one conditional at a time. I've tried looping, but I couldn't get my head round it.

Well, here is the "replace all" thing that I done in MS word to get it like this, phew!

I would really appreciate it if anyone can show me hints or suggestions to how this can be simplified:

Code:
	if ((chosenfile1==1)&&(chosenfile2==1)) statisticsof2textfilescompared ("The Sun","The Sun",".\\textfiles\\thesun.txt",".\\textfiles\\thesun.txt");
	else
	if ((chosenfile1==1)&&(chosenfile2==2)) statisticsof2textfilescompared ("The Sun","The Times",".\\textfiles\\thesun.txt",".\\textfiles\\thetimes.txt");
	else
	if ((chosenfile1==1)&&(chosenfile2==3)) statisticsof2textfilescompared ("The Sun","French Article",".\\textfiles\\thesun.txt",".\\textfiles\\frenchnewspaper.txt");
	else
	if ((chosenfile1==1)&&(chosenfile2==4)) statisticsof2textfilescompared ("The Sun","Romeo and Julliet",".\\textfiles\\thesun.txt",".\\textfiles\\shakespeare.txt");
	else
	if ((chosenfile1==1)&&(chosenfile2==5)) statisticsof2textfilescompared ("The Sun","Harry Potter",".\\textfiles\\thesun.txt",".\\textfiles\\childrensbook.txt"); 
	else
	if ((chosenfile1==2)&&(chosenfile2==1)) statisticsof2textfilescompared ("The Times","The Sun",".\\textfiles\\thetimes.txt",".\\textfiles\\thesun.txt"); 
	else
	if ((chosenfile1==2)&&(chosenfile2==2)) statisticsof2textfilescompared ("The Times","The Times",".\\textfiles\\thetimes.txt",".\\textfiles\\thetimes.txt"); 
	else 
	if ((chosenfile1==2)&&(chosenfile2==3)) statisticsof2textfilescompared ("The Times","French Article",".\\textfiles\\thetimes.txt",".\\textfiles\\frenchnewspaper.txt"); 
	else 
	if ((chosenfile1==2)&&(chosenfile2==4)) statisticsof2textfilescompared ("The Times","Romeo and Julliet",".\\textfiles\\thetimes.txt",".\\textfiles\\shakespeare.txt"); 
	else 
	if ((chosenfile1==2)&&(chosenfile2==5)) statisticsof2textfilescompared ("The Times","Harry Potter",".\\textfiles\\thetimes.txt",".\\textfiles\\childrensbook.txt"); 
	else

Aiiiiiiiiiiiiiii.

There must be some way of making this simpler, there must bee....
