st: Version control questions

[Richard Williams <Richard.A.Williams.5@ND.edu>]

If a main program says

version 8.2

do you also need to include a version statement in any additional routines 
it calls - or will version 8.2 continue to hold?

In Stata 9.0, level need not be an integer anymore, e.g. it can be 
99.99.  Further, looking at the docs for the 9.0 -version- command, I don't 
see any indication that -level- reverts to old behavior under version 
control.  Ergo, for a program written under 8.2, instead of coding 
something like

Level(integer `c(level)')

on the syntax command would it be better to code

Level(string)

and also dropping any error checks for level being between 10 and 99?  I 
know that can delay error checking but I think Stata itself will generate 
errors quickly enough if the level is illegal.

Alas, I am one of those people who STILL hasn't upgraded to Stata 9 so I 
can't check these out myself yet.
