Bill Gould followed up on a question from H�kon Finne and proposed:
> What H�kon needs to have in `brands' is

> `"(make=="Buick Century" | make=="Buick Electra" | make=="Buick Opel")"'
> `"(make=="Datsun 200" | make=="Datsun 210")"'
> `"(make=="VW Dasher" | make=="VW Rabbit" | make=="VW Scirocco")"'
This, unfortunately, leads to the dreaded macro length problem, as these commands show:
. local buicks `"(make=="Buick Century" | make=="Buick Electra" | make=="Buick Opel")"'
. local datsuns `"(make=="Datsun 200" | make=="Datsun 210")"'
. local vws `"(make=="VW Dasher" | make=="VW Rabbit" | make=="VW Scirocco")"'
. local brands `"`buicks'"' `"`datsuns'"' `"`vws'"'
.
. foreach brand of local `"`brands'"' {
2. list price if `brand'
3. }
local macro name "(make=="Buick Century" | make=="Buick Electra" | make=="Buick Opel") too long
r(198);
.
In this case, the macro length problem appears to be due
to some internal problem in how -foreach- is handling macros.
StataCorp, is there a solution?
