I got the following compile warning: EXPLOD.C(238) : warning C4056: overflow in constant arithmetic and a number of link errors like this: @Microsoft (R) Overlay Linker Version 3.61 Copyright (C) Microsoft Corp 1983-1987.

It would be nice if someone could rewrite the code for EGA and include more colors. (I would, but I don't have the time.) > The program apparently goes as fast as it can.

The fireworks repeat endlessly (until you hit ESC). You can apparently slow it down by entering a numerical argument on the command line (which creates more "explosions" and thus fills the screen more). The following is the screen that initially appears before the graphics start, but on a fast machine, it goes by so fast you hardly even see it, let alone have time to read it. It would be a good idea to pause after this message is displayed with a "strike any key to continue" routine. EXPLOD 1.0 by Dennis Lo 89/06/24 Usage: explod [video card] [# explosions] [video card] = 'c' for CGA or 'h' for Hercules. Default is auto-detect, but EGA/VGA users must specify 'c' or 'h'. [# explosions] = # of simultaneous explosions. Default is 8 for CGA and 10 for HGC. For a 4.77 Mhz XT, try 5. For a 8 Mhz XT, try 10. Examples: explod (for 8MHz XT with CGA or HGC card) explod 5 (for 4.77MHz XT with CGA or HGC card) explod c (for 8MHz XT with EGA, CGA mode) explod h (for 8MHz XT with EGA, HGC mode) explod h 25 (for 8MHz AT with HGC card) explod 15 (for 8MHz 80186 XT with CGA or HGC Setting up, please wait... -- Theodore A.
