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?
