NAME global - Access global variables SYNOPSIS global varname ?varname ...? DESCRIPTION This command is ignored unless a Tcl procedure is being interpreted. If so then it declares the given varname's to be global variables rather than local ones. Global variables are variables in the global namespace. For the duration of the current procedure (and only while execut- ing in the current procedure), any reference to any of the varnames will refer to the global variable by the same name.
