A.4.1 Referring to Variables

To refer to a variable which is defined within the same section only its (short) name can be given:

a = 5;
{  a = 10;
   b = a;

In this example variable b in section Section4 refers to variable a in section Section4. Therefore, the value of the variable b equals 10.

Sections can be built up in a nested manner similar to a directory tree. If a variable must be referred to from another section than the current one, the path of the respective variable must be specified. This path can be given absolutely or relatively.
