"A " { $emphasis "range" } " is a virtual sequence with real number elements "
"ranging from " { $emphasis "a" } " to " { $emphasis "b" } " by " { $emphasis "step" } ". Ascending as well as descending ranges are supported."

{ $code "100 1 [a,b] product" }
"A range can be converted into a concrete sequence using a word such as " { $link >array } ". In most cases this is unnecessary since ranges implement the sequence protocol already. It is necessary if a mutable sequence is needed, for use with words such as " { $link set-nth } " or " { $link change-each } "." ;
