Icon Sushi is da best ;). Frankly at least you can normally import alpha channel. I think that in explorer, shell windows and in title bar no matterwhat the icon symbolic name is, first icon in exe file is used. That means first icon in rc script. You can use API to change icon at runtime however.

Re: UNREAL mode

OK. There IS an unreal mode (A BUG of the CPU ???). I can use some 32 bit instructions in the real mode and use the unreal one to access all (??? up to 4 GB ?) memory. But the executable remains limited to the conventinal memory (<cca 500 KB) and affected by the 64 KB BUG. Nevertheless: FreeBASIC D...
