>Macros for Automatic Global Variable Creation</H1
><P
>&#13;    In addition to the macros discussed earlier, a few macros allow
    easy creation of simple global variables. These are nice to know
    in case you want to introduce global flags, for example. This is
    somewhat bad practice, but Table <A
HREF="zend.variables.global.html#tab.macros-global-vars"
>Table 33-5</A
> 
    describes macros that do
    exactly this task. They don't need any <TT
CLASS="envar"
>zval</TT
>
    allocation; you simply have to supply a variable name and value.
