VARKON - 6 min tutorial

Playing with MBS

You have now created a module. A Varkon module is a special kind of computer program that can create drawings and other data. To see your module in text notation, press the MBS button in the menu window.

Varkon will now translate your module to text and call up a text editor to display (and let you edit) the text. This is what it should look like:

GLOBAL MODULE my_first_job();

BEGINMODULE

  poi_free(#1,vec(96.735458419579, 380.28671945701, 0.0));
  poi_free(#2,vec(283.24158285645, 416.90531674208, 0.0));
  lin_free(#3,on(#1), on(#2):PEN=2,WIDTH=2);

ENDMODULE

With your text editor, try to change the PEN=2 to PEN=3, then save the file and close the editor. Varkon now compiles the new text into a new module, replaces the current module with the new module and runs it to create a new result. You will then see a green line instead of the red line in your graphics window.

This is the generic mode of Varkon in a nutshell. What you do is actually a kind of high level geometric programming, interactively or with a text editor. Varkon executes what you program and creates a corresponding result automatically.

In explicit mode you can not create or edit modules interactively, but you can edit what a module has created and you can also create result directly without creating a module.

You can now go to the last section, you have 1 minute left !
