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.

With an extra space it looks like this:

` i '

That referencing has worked for me in conjunction with the -levelsof-
