Example text

Yeah, it does. But instead of exiting, the program will react as if we wrote "-4 THROW" instead of "DROP DROP". The program will correctly report an exception when we enter "0" and act accordingly. This will work with virtually every runtime error. Which means we won’t have to protect our program against every possible user-error, but let Forth do the checking. We won’t even have to set flags in every possible colon-definition, since Forth will automatically skip every level between ’THROW’ and ’CATCH’.

A single number is printed using ’#’ and the remainder of the number is printed using ’#s’ (which is always at least one digit). Let’s go a bit further into that: : print# s>d <# #s #> type cr ; 256 print# This simply prints a single number (since only ’#S’ is between the ’<#’ and the ’#>’ and goes to a new line.

And ’CHAR’ isn’t the only word which is affected. " Hello world" [char] ! ) char ! THEN outside colon definitions. And not only these, others like ’C”” can’t be used as well. Real Forthers call this ”inside a colon definition” thing compilation mode and working from the prompt interpretation mode.
