To those of you who have offered to post graphics routines, for MS/DOS/HERCULES/C machines, I think there is enough interest out there to warrant postings. Whadda I hafta do, beg ? I have seen the kinds of graphics my Herc can produce, and it is incredibly frustrating to be unable to use them ! All *I* need is a "draw line" tool in C (lettuce pref) and I don't care how slow it is. I think there are enough others who would appreciate similar tools. Please post ! live free ! mjr -- Seek on high bare trails Let us arrange these flowers... Moon-lighted mountains!

Re: request for Hercules graphics tools for the IBM PC/XT/AT for the C language. There are a number of commercial packages for producing Hercules graphics with the C language. Here's what I've discovered so far. First, Hercules sells a graphics package called GRAPH X. For a cost of about $45 this allows you to draw vectors, circles, and arcs and do fills. The version I received originally did not include a C binding, but when I called Hercules and requested it, they sent me a copy. It works with Lattice C. In the Hercules Compatible Software brochure they mention that HALO (Lifeboat Associates, $140) and GSX Toolkit (Digital Research, $350) are available for the C language. A package which is powerful for scientific work is GraphiC (Scientific Endeavors, $250) which supports linear, log, semi-log, 3-D, contour, polar, and Smith charts with labeled axes. Screen dump is also supported. IBM's graphics packages all utilize the VDI driver. While IBM does not support Hercules, a VDI driver can be obtained from a third party (Graphics Software Systems, $40) to allow C language graphics control. The one I am using currently is PlotDev (MicroPlot, $39), a resident device driver that allows you to do either Tek 4010 or 4027 emulation with C programs (or practically any other language) using Hercules, EGA, and a number of other graphics boards. We have concocted a home-brew graphics package (called "g_raph") which works on top of PlotDev. It also includes graphics screen dump and is a lot faster than VDI. So there is a lot to choose from for the Hercules board and the C language, depending on how much you want to pay. Sorry, but I haven't seen anything for free.
