[[OPTION _EXPLICITARRAY]] instructs the compiler to require arrays be declared with [[DIM]], [[REDIM]] or equivalent.
{{PageSyntax}}
: [[OPTION _EXPLICITARRAY]]
{{PageDescription}}
* Normally statements like {{InlineCode}}x(2) = 3{{InlineCodeEnd}} will implicitly create an array x(). [[OPTION _EXPLICITARRAY]] requires a preceding declaration for the array, helping to catch mistyped array and function names.
* Unlike [[OPTION _EXPLICIT]], simple variables can still be used without a declaration. Example: {{InlineCode}}i = 1{{InlineCodeEnd}}
