Scope of Block Objects

The scope of an object defines where it is visible, it is the area of the program logic that can legally refer to a given object.

A variable or object's (cursor, constant Etc.) scope is determined by the block that it is declared in. It is only available until the block it is defined in ends execution. Remember that block variables are defined under the DECLARE keyword.

For nested blocks an object defined in a parent block is available within all its child (nested blocks). The reverse is not true, objects defined in a child block are not visible to the parent.

If a nested block defines an object with the same name as an object in its parent block then only the local object is visible. Unlike Java there is no method provided to get at the parent object in this circumstance.
