Boss is going to please with you aint 'e?
"page" is being defined by the foreach.
So for each element in the block "pages" foreach will set the word page to
the value of that element - it then
does the body block with that value.
You can use whatever you want:
foreach qwrtyuiop ["one" "two" "three"] [print qwrtyuiop]
Note that qwrtyuiop only has a value in the body block.
see:
>> help foreach
USAGE:
FOREACH 'word data body
DESCRIPTION:
Evaluates a block for each value(s) in a series.
FOREACH is a native value.
ARGUMENTS:
word -- Word or block of words to set each time (will be local) (Type:
get-wor
d word block)
data -- The series to traverse (Type: series)
body -- Block to evaluate each time (Type: block)
