Description
Dim is used to declare variables and allocate storage space. The required component, nameA, is the name of the variable, it must follow standard variable naming conventions. The optional list of subscripts are the upper bounds of dimensions of an array variable. Up to 60 comma-separated dimensions may be declared. Script level variables are available to all procedures in the script; procedure level variables are available only in the procedure they are declared in. The lower bound of an array is always zero.
An optional initial value can also be supplied. This must be a simple variable, not an expression.
Example
