[REBOL] Re: Undocumented: Index value local to FOR loop

From: greggirwin:mindspring at: 23-Mar-2004 11:04

Hi Giuseppe, GC> I have found this undocumentend behaviour: GC> for indice 1 10 1 [esterno] GC> Rebol tell me that "indice" is not initalized but it is ! This word seems to GC> remain local to the for loop. Yes, FOREACH and REPEAT work the same way. FOR is a mezzanine, so you can see how it works--though it is a bit advanced if you happen to be new to REBOL. Look at the core docs (e.g. core.pdf) at how you can define literal-arguments and get-arguments for functions. REBOL uses 'definitional scoping', which may seem a bit confusing at first when used with literal arguments.

hello 10
>> hello
