Script programming and Graphics examples
If you need general information about the Extcalc script language, please visit the documentation page of Extcalc.
On this page, you can download some example script code,which runs on Concalc and Extcalc and example functions
for graph drawing.
You can download, test and modify this examples. You may also send me your own script programs or functions, so that I can publish them on this page.
When you want to do that, please send the code whith a short description to rainer1223@users.sourceforge.net.
To use script code in Extcalc, open Extcalc, choose the script editor and use the import dialog from the menu script -> import script.
For Concalc, download the code and run concalc -m scriptname.
To import functions for graph drawing into Extcalc, choose the graphics window and open the import dialog from the menu by graphic -> import graphs.
