Forth Tutorials

Recommended Posts

A bit off topic, but I found another vintage computer which runs Forth natively in it's console ROM. =)

Made a classic mistake....

And then I got this........

Disappointed, I re-read the reference card, changed to this:

 

: DRAW
XBAR 7 42 10 HCHAR

 

And then got the desired result. =)

Another difference between TF and TIF. In TIF, this would be

 

: DRAW 7 XBAR 10 42 HCHAR ;

 

Also, it looks like you changed the count from 10 to 20.

Ahh yes, I did... The box was off center, so I changed it to 20. =)

 

Thanks for the catch there.

 

Yea, I actually thought I'd found another misleading section of the TF documentation and I started writing a post about it... Before I sent it though, I re-read the ref card and discovered it was I who was mistaken. Next I'll be re-defining some standard character sets and working toward building my title screen.

It's a VERY interesting machine.... Too bad there's no support for it and no community. =)

 

Still though... would look VERY cool on my war-room desk. =) (once I get it set up, that is.)

I'm pretty sure I followed the TI BASIC conventions with HCHAR/VCHAR/GCHAR with respect to the order of the arguments. I figured if I was going to use the same name as the TI BASIC versions it would be a bit of an insult to change the order of the arguments! However, unlike TIB/XB the number of repeats is not optional!

 

Forth on!
