DOFOR Loop Question

[timduy]

If I write this code:

COMPUTE X = PORT941NA(2007:12)
DISPLAY X

I get what I expect:

1041.50000

If I place it inside a DOFOR loop:

DOFOR JJ = PORT941NA PITT342NA MINN427NA CHIC917NA AUST448NA PHOE004NA DENV708NA NASH947NA OKLA440NA
COMPUTE X = JJ(2007:12)
DISPLAY X
END DOFOR JJ

I get this:

## SX17. Missing Operator or Adjacent Operands
>>>> COMPUTE X = JJ(<<<<

So I can I identify just one entry in the DOFOR loop?

Thank you!

By default, the DOFOR index is an INTEGER, which in this case will run over the "handles" for the series. To pull out an entry from a series you need to add a "cast" to the SERIES type:

COMPUTE X = ([series]JJ)(2007:12)

Again, thank you!
