-===== Dim (Statement) =====
-==== Format ====
-=== Create a One Dimensional Array ===
-**dim** [[variables|variable]] ( [[integerexpressions|array_size]] )\\
-**dim** [[variables|variable]] ( [[integerexpressions|array_size]] ) **fill** [[expressions|expression]]\\
-**dim** [[variables|variable]] [ [[integerexpressions|array_size]] ]\\
-**dim** [[variables|variable]] [ [[integerexpressions|array_size]] ] **fill** [[expressions|expression]]
-=== Create a Two Dimensional Array ===
-**dim** [[variables|variable]] (  [[integerexpressions|array_size_rows]] , [[integerexpressions|array_size_columns]])\\
-**dim** [[variables|variable]] (  [[integerexpressions|array_size_rows]] , [[integerexpressions|array_size_columns]]) **fill** [[expressions|expression]]\\
-**dim** [[variables|variable]] [  [[integerexpressions|array_size_rows]] , [[integerexpressions|array_size_columns]]]\\
-**dim** [[variables|variable]] [  [[integerexpressions|array_size_rows]] , [[integerexpressions|array_size_columns]]] **fill** [[expressions|expression]]
-=== Use a List to Create and Fill an Array ===
-**dim** [[variables|variable]] = [[Lists|{ list ... }]]\\
-**dim** [[variables|variable]][] = [[Lists|{ list ... }]]\\
-**dim** [[variables|variable]] = [[Lists|{ { list ... }, { list ... } ... }]]\\
-**dim** [[variables|variable]][] = [[Lists|{ { list ... }, { list ... } ... }]]
-=== Copy One Array to Another ===
-**dim** [[variables|variable]] = [[variables|variable]][]\\
-**dim** [[variables|variable]][] = [[variables|variable]][]
-=== Fill an Existing Array With a Single Value ===
-**dim** [[variables|variable]] **fill** [[expressions|expression]]\\
-**dim** [[variables|variable]][] **fill** [[expressions|expression]]
-==== Description ====
-Returns a newly created single dimensional array of length //integer// or a 2 dimensional array that can be addressed by //row// and //column//.  By default the elements in the array are left uninitialized (empty), You may add the fill option to fill all elements with a single value.\\
-The first element of an array has an index of 0 (zero).  Indexes range from 0 to length-1.
-The **dim** statement can also be used to create a new array that is a duplicate of another array.  The form "DIM var = var" does this by dimensioning a new array in memory and copying all of the data from the original array.
-==== Example ====
-<code>
-dim z = {1, 2, 3, 4, 5}
-print z[0] + " " + z[4]
-</code>
-will print
-<code>
-5
-</code>
-==== Example Two ====
-<code>
-dim c(4)
-c[0] = "cow"
-c[1] = "brown"
-c[2] = "how"
-c[3] = "now"
-print c[2] + " " + c[3] + " ";
-print c[1] + " " + c[0] + "?"
-</code>
-will print
-<code>
-how now brown cow?
-</code>
