Rename different files to one file name, one at a time

Question

i have files named..

82011.nsf
63113.nsf
55555.nsf

i must rename each file to single.nsf (for example ren 82011.nsf to single.nsf)

then use a program to act on that file (single.nsf)

then rename the next file (63113.nsf to single.nsf) then use a program to act on that file (single.nsf) etc

I want a batch file to do the nename, pause (so i can run the other program), then do the next rename until all nsf files are done.

how?
