Awesome for finding out how things work. :) I also have just added this site to my RSS reader in the hope of new articles appearing shortly. :)

For someone who has had no previous experience with stack-based language, your explanations are quite informative. RSS’ed, and eagerly awaiting the next installment.

“Can integers be entered in hexadecimal or octal form (as literals)?”
– Jon

Yep…you can enter and print numbers as bin, hex, and oct…they will always be stored on the stack in decimal form, but they can be taken out however you like:

(scratchpad) BIN: 101010

--- Data Stack:
42
(scratchpad) .b
101010
(scratchpad) HEX: 2a

--- Data Stack:
42
(scratchpad) .h
2a
(scratchpad) OCT: 52

--- Data Stack:
42
(scratchpad) .o
52

You can also create them from a string with bin>, hex>, and oct>. See “Convert between numbers and strings” by doing "number-strings" help in the listener.
