Re: [Dr. Geo] how to use a input parameter in DrGeo SmalltalkSketch

[address@hidden]

I tried to run the example:

| f ruler a |
f _ DrGeoSketch new axesOn.
ruler _ f float: 1.5 at:0@0 from: 1 to:4.
(f value:ruler parents: {} at: -2@4) name: 'Value from a ruler'.
a _ f value: [ ruler value / 3].
f  circleCenter: 0@0 radius: a.

The code with value:  taking a Block as argument (the Block [ ruler value / 3]) 
seems to work in the latest DrGeo.

David Stes
