Global variables

Global variables can be accessed by all threads in a Desktop session. They are created by prefixing the variable name with ``:''.

For example:

   :count=10

creates a global variable count with the value ``10''.

Global variables can be accessed with the constructs $:var, $#:var, and so forth. Global variables are distinct from local variables with the same name, so you can have:

   count=12

and

   :count=10

as separate variables. However, $var will give the value of the global variable var if no local variable has been defined.
