Code: 

if {[file exists $myfile]} {
And for arrays we can use if the array, list
exists

Code: 

if {[array exists $mylist]} {
But how to check if a global variable exists? inside
a different procedure, or even a local variable?

I am making a script which checks if a global
variable exists from another script, and then
it uses that variable for string matching purpose.
