Thanks a lot Nick.

That seems to almost work, but leaves the last variable in the initial list commod unchanged:

So I get something like tea98 coffee98 sugar98 wheat for commod2. Have tried this with a few different variables and always seems to skip the last one.

Thanks,

Gareth

Such trickery in this kind of context  is also documented at

-- not that I expect anyone apart from me to know or remember that.

Search for "unab" in that FAQ.

I have a large list of variables, from which I have created a local macro:

local commod tea coffee sugar wheat
I also have variables in my data set, which refer to specific years, so I
have variables tea98, coffee98, sugar98, wheat98 etc

I would like to create a local macro referring to each year, so:

local commod98 tea98 coffee98 sugar98 wheat98

local commod99 tea99 coffee99 sugar99 wheat 99

etc.

Is there a way to do this, referring to local commod and adding the the
suffix "98" "99" etc?
