Additional setup 65
If a variable is redefined in its scope, a new value will be substituted after each
redefinition. Thus, the statement:
<DEF __NAME__= "NAME_1
"/>Now you will see the first
value: %__NAME__%.
<DEF __NAME__= " NAME _2"/>Now you will see the
second value: %__NAME__%.
will be output as:
Now you will see the first value: NAME_1.
Now you will see the second value: NAME_2.
A variable can have a macro as its value.
<DEF _var_name_ = "%_macro_name_%
"/>
In this case, the parser will first substitute a macro for a variable and then it will
replace the macro with its value in the current scope.
