Adding axioms In order to add axioms press the "add axioms" button on the main control panel. A new window should then pop up (your window manager will probably ask you where to put it) labelled "xmagic: add axioms". This window will have 18 predefined axioms written in it. There will be also empty slots for 5 additional axioms which you can define yourself. You can add an axiom by clicking on it. The selected axiom will become highlighted. You can delete a selected axiom by clicking on it again. The deletion of the axiom will be marked by the axiom becoming unhighlighted. In order to define your own axioms click on the "define axiom" button. A new window will then appear labelled "xmagic: define axiom". Type in the axiom in the window and press any of the buttons in the bottom line with numbers 19 through 23 on them. The number of the button will define the place of the axiom in the main "add axioms:" table. You can then add this axiom in the same way as with the predefined axiom. You can modify the difinition of any of the axioms 19 through 23 at any time. If you modify a selected axiom, it's modified definition will be passed to MaGIC, and it will remain selected, unless the definition was rejected by MaGIC due to syntax errors.
