[REBOL] Re: "piping" functions

From: jf_allie::hotmail at: 24-Nov-2005 3:45

Volker,
>>Hard to understand what you do not understand, i hope i do it: >>The focus is here >>copy/part B back tail b >>not here: >>copy/part b BACK TAIL B >>copy B >>return a copy of the series on position b. >>copy/part B back tail b >>returns a copy of the series on the position b, but not upto end, but upto >>back tail b
... yes , and what does the last BACK TAIL B evaluates to? an INDEX position? Simply restated, I would like to understand why BACK TAIL B used alone like here:
>>BACK TAIL B
returns a series while when used in:
>>copy/part b BACK TAIL B
it returns a number. (I assume it returns a number because this is what COPY/PART needs as a second argument) Many thanks, JF
