FOR Loops

[John Lewis]

Hi everyone!

I have a number of string values in a series Z (say, Z(1)="firms", Z(2)="cars", Z(3)="legs", Z(4)="shops").

At the same time, I need to use the following FOR statement:

FOT %ARQ firms cars legs shops
....
NEXT

Could you please help how to use this Z series in the FOR statement instead of listing all the string values in the line?

Thank you for all kinds of help!

If they're actually in an alpha series, it is not easy to do with a string loop. You can do it with a number loop though:

Code: Select all

for !i=1 to @obsrange %arq = z(!i) next

Thanks a lot!

Unfortunately I have a problem with aplling @obsrange to a alpha-series Z. EViews states: "Alpha sent to a function which operates on a matrix". Could you please help with this? How to obtain correctly the lenght of an alpha series?

Thank you very much!

@obsrange doesn't require an argument. It doesn't need to be applied to a series. It just tells you the length of the workfile (all series are the same length as the workfile).
