Dear Robson,
Thanks for your reply.
I have tried that already and it just returns: "ambiguous abbreviation". I
also tried it with a macro, namely:
Local i i
And when I then try "avg = rowmean(Lag1 - Lag`i')", STATA actually
interprets it as lag"i", but not with value of variable i.
So my problem persists, I'm not able to address the value of i.
Regards
chris

I think you need to reference Lag"i" using Lag`i'
With an extra space it looks like this:
` i '
That referencing has worked for me in conjunction with the -levelsof-
command.
