Introduction
In the local declaration block:
- Constant
- Variable
can be declared. The local declaration block is located on a procedure level. The declared items can be used within the procedure.
Semantics
Constant
The value of a local constant is set at design time and can not be changed at runtime. Local constants are visible only within its own procedure. A constant has a Type and a corresponding type value.
Variable
The value of a local variable can be changed at runtime. Local variables are visible only within its own procedure. A variable has a Type and a corresponding type the initial value (default value).
