Thank you Thomas & Fred,

Sorry, I didn't answer but I got that function right after Fred's hint to h extended_fcn ...

P.S.
Here's my Code which draws an bar chart if someone is interested in it:
outcome is a probabolity and uvar is 0/1 coded
[snip]
foreach outcome in Y1 Y2 {
foreach uvar in X1 X2 {
gen outcome1 = `outcome' if `uvar'==1
global label1 : label (`uvar') 1
gen outcome0 = `outcome' if `uvar'==0
global label0 : label (`uvar') 0
graph bar (mean) outcome1 outcome0 [pw=phrf] if jahr==2003, ///
over(`uvar' , label(nolabels)) ///
over(alter_gr4) outergap(25) bargap(-90) ///
ylabel(0 "0%" .10 "10%" .20 "20%" .30 "30%" .40 "40%" .5 "50%" ///
.60 "60%" .70 "70%" .80 "80%" .90 "90%" 1.0 "100%" , angle(horizontal)) ///
xsize(3.9375) ysize(2.95) scheme(lean2) bar(1, fcolor(navy*.6)) bar(2, fcolor(navy)) ///
legend(order(2 "\${label0}" 1 "\${label1}" )textfirst cols(2) position(6) symxsize(medium))
graph export "\${arbeitsverzeichnis}Grafiken/deskriptiv/`outcome'_`uvar'.eps", replace
drop outcome*
}
}

Fred Wolfe said to see extended functions... He's right, but you want _macro_ extended functions, so start with macro first.

Here's the diagram for what you want:

{local | global} macname : label { valuelabelname | (varname) } {
maxlength | # [#] } [, strict ]

Thus"
global myvaluelabel : label mylabel 1

And if, say, mylabel was the value label for variable myvar, you could
directly do:
global myvaluelabel : label (myvar) 1
And Stata will figure out which value label you want.

Dear all,

I'm trying to do the following:

. label define mylabel 1 "Hello" 2 "Good Bye"
. global myvaluelabel UNKNOWNFUNCTION(mylabel,1)
. di "{\$myvaluelabel} XY!"
HELLO XY!

But I don't know the UNKNOWNFUNCTION and I didn't find an information about. But I know that it is possible..

(In fact I want to assign the value label to a legend in an overlaid tw graph.. )

I hope someone can help me..

Lars
