| Name: | forallindexed - Call a procedure for each element of a list/string
|
| Synopsis: |
[v1,...,vn] {f} forallindexed -> f(0,v1),...,f(n-1,vn)
|
| Parameters: |
[v1,...,vn] - list of n arbitrary objects or string
{f} - function which can operate on the elements of the
array. f is not required to return a specific number
of values.
|
| Description: |
For each element of the input array, forallindexed calls f with
two arguments, the element and its index within the list/string.
forallindexed is similar to forall, only that the index of the
element is also passed to the function f.
Alternatives: Functions forallindexed_a for a list, forallindexed_s
for a string (both undocumented) -> behaviour and synopsis are the same.
|
| Examples: |
[(a) (b)] {} forallindexed -> (a) 0 (b) 1
