Array variables - Not Recommended

User-defined variables can also be defined as arrays. Array members are referred to with square brackets (For example, A[2]).

Array indexes start at 1. For instance, in A is defined as a 100-entry array, then valid members are from A[1] to A[100]. Any index number outside this range results in a runtime error.

No system variable is an array. Interaction variables cannot be defined as arrays.
