array=String[3] -- make an array of three Strings
array[0]='String one' -- set each array item
array[1]='Another string'
array[2]='foobar'
loop i=0 to 2 -- display the items
say array[i]
end
This example also shows NetRexx line comments; the sequence
-- (outside of literal strings or
/* comments) indicates that the remainder of the
line is not part of the program and is commentary.
NetRexx makes it easy to initialize arrays: a term which is a list of one or more expressions, enclosed in brackets, defines an array. Each expression initializes an element of the array. For example:
words=['Ogof', 'Ffynnon', 'Ddu']would set words to refer to an array of three elements, each referring to a string. So, for example, the instruction:
say words[1]would then display Ffynnon.
