DIM Miscellaneous Command
ACTION: Declares an array variable and allocates storage space.
PROGRAM SYNTAX: DIM variable(dimension,dimension,etc)
DIM variable$(dimension,dimension,etc)
REMARK: The “option base zero” for array notation is used, in which the first ele-
ment of each array dimension is annotated as element “0”. Therefore,
the total number of elements in the array is: (dimension1 +
1)*(dimension2 + 1) * ... *(dimension n +1).
Example notation for a two-dimensional array:
