Hi Nick, thanks for your response.

Would it be possible for you to give an example of how to clone -egen- to add a -replace- option, or alternatively define say -regen- that does both -egen- and then -replace-?

Many thanks

No. You want a -replace- option for -egen- and it doesn't have one. I
think the idea is reasonable but there is no such option. The fact is
that typing -replace- would be about as much work as the alternative,
particularly given that your three-liner can be two lines:

drop y
bysort x: egen y = myfunc(y, a, b, ...)

You could certainly clone -egen- to add a -replace- option.

Nick

P.S. I would avoid the word "screwed" on Statalist. Also, there are no
macros (Stata sense) in your question,
