st: Re: Use of subinword in Stata 13 vs. Stata 12

[Dirk Enzmann <dirk.enzmann@uni-hamburg.de>]

Thanks Chamara,

the issue of using = is a good observation. However, not to use it is 
not really an option because the local macros are created by -syntax- (I 
came across this problem because -subinword()- did not work as expected 
when using local macros created by the -syntax- command).
