Then Stata 8.2 informs me
'i' invalid name

Your problem is the single quotes. The left single quote is ` (grave).
It may be on the upper left corner of your keyboard, or it may be
elsewhere. It may also be a dead key, displaying nothing until you hit
the spacebar.

The Stata manuals are not very explicit on this, and you are not the
first who had this difficulty.
