If you want to write a program that alters elements of very large lists you can alter single elements with largelist[[elementnumber]]=newvalue; However, if you want to do this with a large string you have to do something like largestring=StringTake[largestring,{1,elementnumber-1}]<>newvalue<>StringTake[largestring,{1,elementnumber+1}]; The problem with this is it requires making a whole new copy of the string to change just one element. This will really slow a program down if you are working with large strings or have to repeat the process many times. Does anyone know a way around this? Dustin Soodak
