Q:

GAMS listing file in Promo API

I'm running the GAMS/Pyomo API for the first time.  The GAMS output says there was a problem during solve, and to check the listing file for details.  But I can't find the listing file.
I searched my entire MacBook for any *.lst files, and nothing.  So my main question is, where does GAMS spit out a listing file when it is called from the Promo API?  Is it in some temporary directory that my terminal can't search?

A:

Try running the solve with the keepfiles=True flag turned on
