You would need to be more specific.

My guess is somthing like this

Code: Select all

set globalvar "value"
proc thisproc {} {
  global globalvar
  puts stdout "PROC $globalvar"
  set globalvar "value2"
  puts stdout "PROC $globalvar"
}

puts stdout "NORM $globalvar"
thisproc
puts stdout "NORM $globalvar"
