Explain the concept of "dynamic scope" in COBOL and how it affects variable visibility.
- Dynamic scope allows variables to be visible based on the program execution path
- Dynamic scope in COBOL is not supported
- Dynamic scope is related to runtime memory allocation
- Dynamic scope is used for handling errors dynamically
In COBOL, dynamic scope refers to the visibility of variables based on the program's execution path. Variables can be accessed based on the sequence of program calls during runtime, affecting their visibility and accessibility. This dynamic behavior is essential in certain program structures and scenarios.
