Re: windows on a multi task machine vs single task

The AES do not shift around window handles. Once you got a valid one, you can trust it doesn't change during program lifetime (unless you change it yourself).

If this is what you were asking for.

Re: WINDTAB AND THE AES WIND_xxx FUNCTION

I only had a brief look into your code and do not understand much about GFA.

Nevertheless, it appears your code opens four windows but attempts to close 5. That's begging for trouble.

Re: Window refresh problems under Geneva/Neodesk

I only peeked briefly into your code (and thus surely didn't understand everything) but you seem to ignore the fundamental rules of AES: you can't just draw something somewhere on the screen. It's the AES that has control of the screen, not you. With GEM AES, you almost never just draw something on ...

Re: movea.b movea.w why these exist?

I wonder what happens when an interrupt happens to occur just while the stack pointer is odd due to the code above. Address error? The stack pointer never becomes odd. It will point to the (superfluous) zero byte that gets pushed to keep it even. Pure C libraries, for example, are famous (at least ...

Re: correct pattern for I/O in GEM app?

If you want to avoid ugly redraw lags in your GEM application, you will need to add timer events to your event loop at a reasonable frequency. The handler would then check if there is something to do using Bconstat(). Due to the nature of this call (you can only check if the receive buffer contains ...

why do you set char_mfdb.fd_w and char_mfdb.fd_h both to zero?

They need to be set to the width and height of your font data source raster form (8 and 12).

For a SCSI bus to work reliably, it must be properly terminated both ends. Anything else *might* work (more or less by chance), but doesn't necessarily need to.
