Betreff: Re: st: RE: confused with syntax graphing points

Nick writes "When a graph command gets complicated,  I tend to copy it  
to the do-file editor and space it out so that I can see the  
structure. If it looks worth keeping,  keep it as a do-file."

I've often created circumstances where a project do-file gets very  
long and unwieldy. Are there any books/articles that provide  
architectural guidance on how to build multi-part Stata projects (i.e.  
data import, prep, analysis and graphing) so that it's more manageable?
