Questions tagged [clipper]

Clipper is an xBase compiler that implements a variant of the xBase language. Use this tag for questions about coding in that language. For questions about the line and polygon clipping library use the tag clipperlib instead.

Use this tag if your question is about one or more aspects of the clipper compiler and/or the xBase language it uses.

Some topics that can be asked are:

  • DOS Development Under Windows
  • Automatic Build And Make
  • The Debugger
  • Form And Menu Editors
  • Graphics-Mode Support
  • Mouse support
  • Protected-Mode Development
  • The enhancements/extensions added.

Above topics are found on the current product website

For questions about the Clipper library, a line and polygon clipping library, use instead.
