Here's a sample program you can actually run through tclsh or wish:
proc main {} {
global var1 var2 var3 var4
set var1 aaa
set var2 bbb
set var3 ccc
set var4 ddd
return
}
proc UseVars {} {
global var1 var2 var3 var4
puts "vars 1 to 4 are: $var1 $var2 $var3 $var4"
}
main
UseVars
exit
Here's an actual run where I pasted the code into an xterm running tclsh:
sys4:/prg/rickm> tclsh
% proc main {} {
global var1 var2 var3 var4
set var1 aaa
set var2 bbb
set var3 ccc
set var4 ddd
return
}
proc UseVars {} {
global var1 var2 var3 var4
puts "vars 1 to 4 are: $var1 $var2 $var3 $var4"
}
main
UseVars
% % % % % vars 1 to 4 are: aaa bbb ccc ddd
...RickM...
