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. |
