Setting the Default Values

You can assign default values to any of the variables and derived data types. This is useful for programs that need to be set to a specific value prior to them being executed.

You can define default values in a VAR block (in which case, they cannot be overridden) or in a TYPE block (in which case they can be overridden by values in the VAR block).

The following sections describe the formats for entering default values:

• Default Values for Built-in Data Types (Literals)
• Default Values for Derived Data Types
• Default Values for Enumerated Data Types
• Default Values for Structured Data Types.
