Pass more than one variable to the foreach loop ??

hello,

I have one row in CVS source file with multiple variables whicha rea read into i.e. serial1,serial2,serial3,location1,location2,location3. Each time I execute block in a loop I need to pass serial1,location1, for next loop execution serial2,location2 and so on but Foreach is able to get only one variable. How can I do that to pass two variables???

greetings
