=== Compiler Issues ===
Several compiler errors have been identified that are caused by using expressions inside of array index brackets. The standard papyrus compiler sometimes compiles expressions inside of array index brackets incorrectly, leading to unexpected behavior and data corruption. As a result, it is recommended to avoid using complex expressions or function calls inside of array index brackets when possible. '''[http://forums.bethsoft.com/topic/1491368-weird-array-index-behavior/ See this discussion]''' for further details and analysis of the problems outlined below:

<br>
*Using complex expressions inside of the index brackets of an integer array can cause unexpected behavior -
<syntaxhighlight lang="papyrus">
;these work fine:
myIntArray[i] = newValue
myIntArray[i * 5] = newValue

;this will result in unexpected values being inserted into the array at run time:
myIntArray[i * 5 + 1] = newValue
</syntaxhighlight>
<br>
*The array Find() function should not be used within an array's index brackets; it can also cause unexpected results -
<syntaxhighlight lang="papyrus">
;this works fine:
i = myArray.Find(none)  ;(find the first blank element)
myArray[i] = newValue   ;(and fill it with our newValue)

;this will result in values being inserted into unpredictable indices of the array at run time:
myArray[myArray.Find(none)] = newValue
</syntaxhighlight>
