We are about to switch to a new forum software. Until then we have removed the registration on this forum.
I am learning Forth with "Starting Forth" and "Thinking in Forth" books by Leo Brodie.
I need to visualize how works the stack...and then write a processing sketch.

Are you trying to create a Forth emulator?
No. It is only a calculator with an unlimited (almost) stack manipulable with Forth WORDS (dup, drop,...).
New functions:
- complex arithmetic
- time arithmetic
I'm working to solve some small bugs :)
The sketch is complete :)
I use it in my daily work.
Thanks for watching.
