Hi Michael,
I'm glad that works for you now. RE your question, the "`" (I'm not sure what it's called either! Sorry, a quick google says it's a "grave accent", I just learned something new) tells Stata that what follows is a macro name it, which you have defined. The "'" tells it that it's the end of the name of the macro you are trying to call. So, when the code runs Stata knows that what is written between "`" and "'" is a macro name and it should place in there the contents of the macro, which you have defined earlier in the lines local truea0, local truea1, etc.
If you exclude either the leading "`" or the lagging "'" Stata will most likely complain.
I hope this helps.
Cheers,
Rodrigo

Subject: Re: st: RE: trying local command
Thanks Rodrigo; works just fine!
A minor question, if I might bother you: in the -gen- command line,
what is the function of the character immediately preceding each
local macro name "`"? On my computer, it's on the upper left corner
of the keyboard, on the same key as tithe, "~".
