GPDL Variables
Variable names in GPDL can be of any length and are case-sensitive. System function names alway start with a dollar-sign. You should probably not start your variable names with a dollar-sign although it is not prohibited.
As in 'C', variables are local to the function in which they are defined. They cannot be referenced from outside that function. For example:
$FUNC checkForMushroom (characterClass)
{
$VAR x;
x = "yes";
} checkForMushroom ;
$FUNC disolveBadges ( )
{
if (x == "yes") // Compiler error...There ain't no x defined!
{
etc.
};
};Variables are allocated on the stack when a function is called. This means that recursive functions get a new copy of local variables each time it calls itself.
