Hello everyone,

How can I ensure that variables in my home made function do not  
conflict with variables with the same name outside the function?  Say  
I have a variable, t, whose value in my notebook is 17.  I've brought  
in a function from another notebook, myFunction, that contains a  
variable named t, and in running the function, t will take on a  
value.  Unfortunately, both t's are the same.  Is there any way to  
make the t within the my function a local variable just like index  
counters in the Table and Do functions?

Regards,

	Greg

t=17

myFunction[x_]:=(t=someOtherValue; rest of function here)
