Thanks. That might actually work but I'm not sure--it seems that GNAT is determined to either open a terminal when an Ada program runs or do nothing at all, as indicated in my reply to Jeffrey about embedding it in an Applescript.

Platypus does create a proper application package so it is double-clickable. Could work.

This reminds me that  few years ago I wrote an extensive Ada wrapper around a similar project called Pashua https://www.bluem.net/en/projects/pashua/. With Pashua and my Ada work, you can run a significant subset of Mac GUI things easily written in Ada--it's just not a proper application bundle however, so it does not solve my immediate need.

I don't think the Pashua author includes my work with his distribution so if this interests anyone, let me know.
