Arrays
 
I am going to assume (quite logically) that arrays index themselves from 0 as in almost all computer langauges.

This is from the documentation:

arrget

Code:
Syntax: %arrget(arrayname,index)

 Return an element from an array. This is like arrayname[index] in other languages. If you ask for an element that is not in the array, a null string is returned. Index values start at ZERO.

 Examples:

#VAR a %array(1,"test","hello")
#SHOW %arrget(a,2)

 displays:

test


Alas, the output is actually 'hello' not 'test'.

However, sometimes I see nothing and sometimes I see the word. Not sure what is happening there.

I would assume you are correct.

0=1
1="test"
2="hello"

It seems like a typo in the documentation, nice catch.
