Re: Announcing JGNAT public version 1.0p

I want this to be cross-platform, so a Windows specific answer wouldn't work,
and I don't want to need to be present and install software (i.e., I want a
truly naive user to be able to just copy it over), so any complex set-up is
out.

However, another user wrote me to say that ada2jvm, a part of the JGNAT package
would do just what I was asking (or was that jvm2ada? need to check it again.).
This will let me do the screen designs in Java, where there are tools around
and portable libraries that will (almost always) already be installed, and the
drive them with an Ada main program that calls the screens to get information.

(I believe that JNI would require that the Java program be the main routine,
though I haven't checked that out in detail.)
