Herkforth interface
As you can see in the herkforth screenshot, the interface always displays:
- the block title (first line in the shadow block)
- data stack
- source code for current block
- source for the word under the cursor (if applicable)
- a little i/o history
- input buffer
You can use this interface as a simple interpreter by typing words/numbers and using the RETURN key after each one.
You can enter words/numbers into the current block by hitting space after you type a word/number.
herkforth command keys allow you to do many more things. Unfortunately, the only way to learn to use the interface is to read about the command keys. Be sure not to miss SHIFT-T.
