Has anyone used a rotation sensor with pbFORTH? I can't seem to get it to work. My test script is attached.

(...) Yes, it's not in the hFORTH (ANSI) standard. You can always do SWAP 0< instead. The new release I'm working on does define 0> .... As a workaround, you can define 0> as above, and then remove the alias later. Cheers, Ralph Hempel - P.Eng (...) (25 years ago, 3-Jun-99, to lugnet.robotics.rcx.pbforth)

Hi Ralph, I'm able to use <, =, >, 0<, and 0=, but 0> is not defined. Any idea why? Thanks, Jonathan (25 years ago, 3-Jun-99, to lugnet.robotics.rcx.pbforth)

(...) The light sensor is an active sensor, which means that it requires power to operate. When you call ds_passive, you are no longer supplying power to the sensor between readings.

Some months ago, I posted this question, but got no response. I've finally played with it some more this morning and have some observations: 1) After setting ds_active, my light sensor returns values of 0-100, as I should. 2) After calling (...)

Following some discussion about the topic a few weeks ago, I was sufficiently curious and motivated enough to write a floating point library for the H8/RCX.
