Joy - JOY driver for GEOS that supports only joystick, not current pointing device. Tgi - TGI driver for GEOS that supports both 40 and 80 column modes but mode can not be Both 40 and 80 column modes are supported GEOS 2.0 so color functions are disabled. This implementation assumes that one character does fit in 8x8 cell, so output withĭefault BSW font, which is has 9 points, might be a bit messy.
RAM drives emulating these should work.Ĭonio - simple console input-output is available for command line applications. If you don't need long strings simply use functions from the Kernal,ĭio - direct disk access is available, but you might have problems with devices other String functions like strcmp, strcpy are doubled with native CmpString,ĬopyString because the latter can handle only 256 byte strings. memset is an alias for FillRam), however not all are supported. Whenever possible native Kernal functionsĪre used (e.g. GEOSLib supports a subset of the standard cc65 libraries. Package and my GEOSLib you are able to create GEOS applications in no time. It is possible now - with Ulrich von Bassewitz's cc65 The designers of GEOS created a flexible and powerful system, whichĬoding GEOS in C? That's something new. GEOS seems very difficult and cryptic for many people, from programmer's point What do you have and what to do with it?Īs we all know that the best computers in the world are the C64 and C128.
