Description:
DIM declares array variables and dimensions the arrays that a program will utilize.
•A DIM statement can appear anywhere before the first use of the array in a
source program. However, when possible, you should place all your DIM state-
ments together near the beginning of the program and should not place them in
the program execution loops in order to prevent errors.
• Up to 2-dimensional array variables can be declared.
