Generating unique filenames.

Hi,
I am trying to create unique filenames for my output text file. The idea is
that I would like to append a string to ".zsc.txt" so that all my files are
uniquely named but with a similar format. I have tried adding the string
variable to ".zsc.txt" while creating the output file name, i.e.
write.table function, is what I have tried using :

write.table(x, file=str,".",".zsc.txt"....);

but it isn't working.

Would appreciate everyone's input on the matter. Thanks :)
