Global variable are variables which retain their value from one execution of a macro to another. They are similar to static variables in C++ or assignable typed constants in Pascal.

 

In the Q++ Macro Language, global variables are declared in the global section of a Macro.

 

In the next sections, we will see how Global Variables must be initialized,  understand how to take advantage of their scoping rules, cover the  precautionsthat must be followed in using them, and see some examples of their use.
