This can be found in the middle of a colon-sequence between `:` and `;` primitive code = [p4_spy_exit] `;SPY``( -- )``` => `"EXTENSIONS"` compiles `((;))` which does `EXIT` the current colon-definition. It does then end compile-mode and returns to execute-mode. See `:` and `:NONAME` compiling word = [p4_spy_semicolon] `SPY_ON``( -- )``` => `"EXTENSIONS"` change the runtime-code of `(NEST)` to call a special word that prints info to the screen whenever a colon word is entered. It will print the name and the current stack, and results in a kind of execution trace over `SPY' :`-colon nested words. primitive code = [p4_spy_on] `SPY_OFF``( -- )``` => `"EXTENSIONS"` disable `SPY_ON` nest-trace. primitive code = [p4_spy_off]
