$dynamic - make arrays dynamic by default
The $dynamic metacommand appears in the program as part of a remark,
either after the rem keyword or after a single quote. The appearance
of this metacommand implies that an array dimensioned with the dim
statement will be dynamic rather than static (see dim). This implication
overrides any previous $static metacommand and may be overridden by a
subsequent $static metacommand (see $static).
If no $dynamic or $static metacommand appears and no other
condition implies dynamic, arrays will be static.
b(9) = 42
Creates a dynamic array, a, with five elements, erases it and redimensions it
with six elements. Note that the array, b, is a static array despite the
$dynamic metacommand because the array is not dimensioned by a dim
