QUICKCALC BASIC Documentation
On-line documentation is provided with QuickCalc. The documentation is accessed via the HELP menu, and the various documents are viewed with Adobe Acrobat Reader. These files are installed along with the QuickCalc executable, so you don't need to be on-line to read them. You may view them here, if you like, before downloading, but there is no need to download these documents individually.
Technical Papers (more advanced math, but interesting stuff)
