Qualifying variables and changing the point of view in C and C++
Qualification is a method of:
- Specifying an object through the use of qualifiers
- Changing the point of view
Qualification is often necessary due to name conflicts, or when a program consists of multiple load modules, compile units, and/or functions.
When program execution is suspended and z/OS® Debugger receives control, the default, or implicit qualification is the active block at the point of program suspension. All objects visible to the C or C++ program in this block are also visible to z/OS Debugger. Such objects can be specified in commands without the use of qualifiers. All others must be specified using explicit qualification.
Qualifiers depend, of course, upon the naming convention of the system where you are working.
