Lists
Lists are an ordered collection of expressions separated by commas and surrounded by a pair of square brackets.
Elements of a list can be accessed by assigning the list to a variable. Lists are 1-indexed meaning the first element starts at index 1.
Lists elements in a variable can be accessed using an integer, range or a list of integers.
Examples
Creating Lists
[1, 2, 3, 4, 5]
1:10
@[10]
Accessing elements in a list
a=[10, 20, 30] a(1)
a=[10, 20, 30] a(1)+a(2)+a(3)
Accessing elements in a list using a range
a=[1, 2, 3, 4, 5, 6, 7, 8, 9] a(2..5)
a=[1, 2, 3, 4, 5, 6, 7, 8, 9] a(1..$ -> 2)
Accessing elements in a list using another list
primes=[2, 3, 5, 7, 11, 13, 17, 19, 23] primes([2, 5])
Accessing elements from the end using the index and size operators
a=[1, 2, 3, 4, 5, 6, 7, 8, 9] a(#$)
a=[1, 2, 3, 4, 5, 6, 7, 8, 9] a(#$ - 1)
Combining lists using the transformation operator
[1, 2, 3, 4] -> [5, 6]
Sublists using the transformation operator
[1, 2, 3, 4, 5, 6, 7, 8, 9] -> 2..5
[1, 2, 3, 4, 5, 6, 7, 8, 9] -> 6..$
[1, 2, 3, 4, 5, 6, 7, 8, 9] -> (1..$ -> 2)
Deleting elements in a list using the index operator
[1, 2, 3, 4, 5, 6, 7, 8, 9] -> #2..5
[1, 2, 3, 4, 5, 6, 7, 8, 9] -> #6..$
