You can also create a variable in a specific namespace. In the following example, the x variable is created in the aa namespace:
aa:x = 1;
Preceding local variables with the Local() function is another option. Both a and b are local variables in the following expression:
Local( {a = 1, b}, ... );
Scoping operators also distinguish a global variable from a local variable. See Rules for Name Resolution.
The following sections describe functions that help you manage variables.
