global -- Bring global into scope
Syntax: global ?varname ...?
Brings global variable(s) varname into scope in a
proc body. This command has no effect if called in the
global scope.
TCL Differences
At the script level, global works the same in Molt as in Standard
TCL. However, Molt's internal implementation of variables is currently much
simpler than standard TCL's, e.g., no arrays, no namespaces.
