Is PATHLST an internal variable? I tried to define and export it as  
environment variable, with no effect. Seems only the -IATS command line  
option has an effect. Still about this option, I noticed it does not appear  
in the help displayed by `patsopt --help`.

As of now, PATHLST cannot be set using an environment variiable.

We could introduce ATSPATH and ATSPREPATH in the future. Let’s wait a bit.On Mon, May 11, 2015 at 2:32 PM, ‘Yannick Duchêne’ via ats-lang-users \< [ats-lan...@googlegroups.com](mailto:ats-lan...@googlegroups.com)\> wrote:
