Summary:
Bounded-length version of the list-length predicate
Version:
21-AUG-93 (26-FEB-91)
Description:
Many Prologs have a built-in function length/2 that can be used either
[1] to determine the length of a given list; or
[2] to non-deterministically create longer and longer lists.
This package defines a function length_bounded/3 with the following
specification:
length_bounded(?L,?Len,+Max)
"L is a list of length Len, where Len<=Max".
Like length/2, it can bind L to successively longer lists when Len is
unbound, but subject to the constraint that Len<=Max. It uses ":-wait"
declarations and hence needs to run under Sicstus Prolog.
Requires:
Ports:
Runs in Sicstus Prolog.
