Dear All
there was a question asked earlier on Fri, 19 Dec 2003 regarding
defining functions in Stata, but essentially no answer was given (or
none that I could find). Nick Cox pointed to the manual (I don't know
which edition, but "saving results" is now 18.10 of [U]). This part of
the manual does not describe the functions though.
Here are some observations:
Observation 1: some Stata commands return functions, e.g. -regress-
returns e(sample)
Observation 2: it is possible to get a list of defined functions by
reading extended macro function:
sysuse auto
regress p w
display `"`:e(functions)'"'
Observation 3: none of the official .ado files eshibits this feature
Observation 4: none of the user commands that I've seen uses this feature.
If there is any new information available now, that was not available
in 2003 I would be glad to hear that.
Why do I need to know this? I am writing a command that automatically
processes the results saved in r() e() s() and at the very least I
need to know whether any user-defined command could, can or will be
able to save anything in the "functions" section.
Thank you,
Sergiy Radyakin
