Looping over two locals at the same time?

[Cynthia Inglesias]

Dear all

Suppose i have two lists stored in two different locals:

list1 one two three four five
list2 six seven eight nine ten

I would like to loop over each list but the loop is like 50 lines long. I was wondering if it is possible to loop over both locals at the same time? And store "results" relating to each list separately?

foreach x of local list1 list2 {
.
.
.
local result1 = one1 two1 three1 four1 five1
local result2 = six2 seven2 eight2 nine2 ten2
}

Or is there another way of doing this without looping?

Thank you.

Your specific syntax is illegal as foreach only allows one local: see the help.

If it makes sense otherwise, you could go

foreach x in `list1' `list2' { 
}

or

local list `list1' `list2'  

foreach x of local list { 

}

Thanks Nick. I am aware that this syntax is illegal but this is the fastest implementation and i was wondering if there was an equally good way to do what i want. Also, how can i know when the loop changes from list1 to list2 so i can save the results in different locals?

If you want two loops you can have them. I thought you were asking for one. Also, if you know that something is illegal, do say.

forval i = 1/2 
        foreach x of local list`i' { 

        } 
}
