Obviously you are a discriminating person 
you knows exactly what you want from Stata. 
Sooner or later you will have to become 
a programmer. 

I am not quite clear how your percents 
are to be calculated, over all the values 
or within each group. 

Here is one way for the first case. You know that there are 
69 values for which -foreign- and -rep78- 
are not missing. You ask for a -catplot- 
showing frequency. But you fix the y axis
so that it shows percent. A tool for 
doing this is -mylabels- from SSC. 

. mylabels 0(10)40, myscale(@ * .69) local(la)
0 "0" 6.9 "10" 13.8 "20" 20.7 "30" 27.6 "40"

. catplot bar rep78 foreign,  blabel(bar, position(outside))   yla(`la') ytitle(percent) 

So, for example, the label "40" appears at 
where 27.6 would be shown on the frequency
scale, because 40% of 69 is 27.6.
