RE: st: RE: command's options as macro

The value of the macro is not different than what is displayed.
Display requires that you put text in quotation marks otherwise it tries to
evaluate the expression as a numeric value.  So you use the quotation marks
with display because it's part of the display syntax for displaying text.
You'd use the quotation marks even if you were not using a macro.

Whatever context you use it in Stata will expand `note1' as: 
note(" 1 2011" )
(which, you'll note, IS what was displayed)

If you need that string to be in quotation marks (as with the display
syntax) you have to put the macro in quotation marks.  Otherwise you don't.

You'll have to explain what " i tried without quotation marks still no
luck." means.  What did you type?  What error did you get?

My recommendation with when having trouble with these sorts of things is
always to get the syntax right without macros, then add the macro.  So, in
this case, write out the tsline syntax so it works exactly the way you want
it to.  Then figure out which pieces you can substitute in with a macro.
So first, does -tsline hits, note("1 2011") - work?  If not, figure out why.
If it does then make sure that the local macro has been defined in the same
session (remember that if you've just run a dofile that defines a local
macro you won't be able to access that macro from the command line
afterwards because that's not the same session from Stata's perspective).
Then make sure you actually typed the macro right.  I'm basically guessing
at potential problems here since you didn't show what you actually typed.

so the value of macro acutally is different than what is being displayed.
when I say 

di "`note1'"   I get 
note(" 1 2011" )

isn't note("1 2011") xerox copy of "`note`'"? 

i tried without quotation marks still no luck.
