Yea, no stack-hungry applications...
Just to be sure, do you plan to add an automatic stack boundary alignment to
HAT word?
I think it could be a good solution.
And memory, you are right, with Forth we have enough memory ;->

Aha, you can control LCD segments directly through the port, right?
Did you try it?

Wow, that's would be really cool!
Let's do it!
(and here you are, ready logo for pbForth - like this picture with NQC on LCD
;)
BTW, looking in ROM listing recently I just realized that there are a lot of
useful data there.
For instance, could be nice to see current type of the sensor or mode of the
motor, etc.
Something like SENSOR_TYPE@, MOTOR_MODE@, ...
What do you think about this?
