Local a$[3]
a[1] = "harry"
a[2] = "franky"
Local b$[3]
b[1] = "harry"
b[2] = "franky"
	
Local temp_a$[a.length]
Local temp_b$[b.length]
temp_a=a[1..2]	
temp_b=b[1..2]

Print "a length: "+a.length

Print a[1]
Print temp_a[0]
Print temp_a[1]

Print b[1]
Print temp_b[0]
Print temp_b[1]

I set up 2 arrays a[3] and b[3]
then I setup 2 more to hold some slices
temp_a[a.length] and temp_b[b.length]

but when I try to access temp_a[1] it doesnt seem to exist

From the Slices doc :

The length of the returned slice is always ( EndIndex - StartIndex ) elements long, even if StartIndex is less than 0 or EndIndex is greater than the length of the string or array.

You're slicing 1 array entry from index 1 and writing it to Temp_a position 0
