st: label value (continued)

[Jean Bouyer <Bouyer@vjf.inserm.fr>]

Thanks Nick for your answer. I think I can get by with it. However, 
may I come back to my question in another way, as I think that beyond 
it, there is something about macros (or about : label) that I don't 
understand.

I don't understand why this works (where v is a variable with a label value)

local n=6
local ll=v[`n']
display "`: label (v) `ll''"

and this doesn't

local n=6
display "`: label (v) v[`n']'"
(Stata answers invalid syntax)

I have noted also that this doesn't work either
display "`: label (v) v[6]'"
(Stata answers invalid syntax)

Thanks

Jean Bouyer
