Problem solved, but reason unknown! Although the following two lines  
of code appear visually identical to you astute Statalist members,  
they are not functionally identical in my Stata10's do-file editor:

. joinby group using a.dta
. joinby group using a.dta

I discovered this accidentally when comparing the command I sent in my  
outbox:
. joinby group using a.dta

to what appears below as received from the Statalist server:
> . joinby group


and then manually retyped the line in the do-file editor, where it  
works splendidly.

Notice the missing "using a.dta"! Must be some display/format code  
lurking in the text. So now my question becomes: isn't the Stata do- 
file editor a text editor that doesn't copy display/format code with  
text copied and pasted from another application, such as a word  
processor?
