9.2.2.1 Local label symbol and scope
This debugger supports both global label symbols, which can be referenced from the whole program
area, and local label symbols, which can only be referenced within the file in which they are declared.
The effective range of local label symbols is known as the scope, which is measured in units of object
files. The scope is switched in this debugger in the following circumstances:
•
When a command is entered
The object file that includes the address indicated by the program counter becomes the current
scope. When the SCOPE command is used to set the scope, the specified scope is the active scope.
•
During command execution
The current scope automatically switches depending on the program address being handled by
the command.
