ROUGOL logo Welcome to
RISC OS User Group Of London



ROUGOL is a not-for-profit organisation consisting of RISC OS users in London and the south-east. Our aim is to bring those users together. There is no membership fee and entry to all meetings is free. To find out more, email us.


Meetings are held on the third Monday of every month. Most meetings feature a guest speaker, demonstrating the latest hardware or software, giving tutorials of software both new and old, or simply to kick off discussions on the current hot topic. Entrance is free, so why not come along and say hello?

Next meeting - Monday 16th July 2018 
DrawScript - David Lane

DrawScript is a programming (or script) language for producing line-drawings in Draw format. The language used is BASIC extended with extra graphics commands. DrawScript is capable of producing much more elaborate drawings than could be created manually only using a mouse, as shown by the examples in the DrawScript gallery.

David will describe in more detail what DrawScript is and what it does, demonstrating some simple examples that come with the software as well as some of his own programs. Uses of DrawScript will be given and some bugs discussed. DrawScript and BASIC programs that relate to one of the many proofs of the rectangular tiling theorem will be demonstrated.

No preparation or knowledge of DrawScript is necessary as all will be explained. If, however, you have the program (download here) you are encouraged to experiment and suggest your own uses.

A question from David: Can you get DrawScript to produce more than one Draw file from one program? David has also suggested that everyone brings a pencil and paper to draw diagrams!
