Re: st: Mata version control

[Partha Deb <partha.deb@hunter.cuny.edu>]

Hi Ben,

I do have access to Stata 9 on another machine so can compile there, but 
it is less convenient, hence my initial question.  I am puzzled, 
however.  -help [M-2] version- seems to suggest to me that it is 
possible to compile with an earlier Mata version.

"    In syntax 1, Stata's version command (see [P] version) sets the version
   before entering Mata.  This specifies both the compiler and library
   versions to be used.  Syntax 1 is recommended."

Perhaps I misunderstand this.

Best.
