Math Parser in Delphi 2009
Delphi 2009 requires that the bcParser.pas file is compiled as a bpl package before it can be installed as a component. You can create a new package project in Delphi and add the bcParser.pass file. You right click
to build, and then right click to install on the package project. Then it appears in Delphi Component Palette.
Alternatively, you can include the bcParser.pas file as a source file into your application project and use it as a library as well.
