Is there a way to exit 2 subs if 1 has called the other. eg:

Sub 1
code......
code.....(if criteria met then)
Sub2
Code...
End sub

Sub 2
Code....
exit sub(this sub and sub1 if certain criteria not met)
else continue
code
end sub
I know I could set a variable to true or false, but was wondering if
there was a way to just exit all subs/macros.
