@@ -620,8 +620,8 @@ Variables can be explicitly set to be universal with the \c -U or \c
local with the \c -l or \c --local switch. The scoping rules when
creating or updating a variable are:
-# If a variable is explicitly set to either universal, global or local, that setting will be honored
-# If a variable is not explicitly set to be either universal, global or local, but has been previously defined, the variable scope is not changed
-# If a variable is explicitly set to either universal, global or local, that setting will be honored. If a variable of the same name exists in a different scope, that variable will not be changed.
-# If a variable is not explicitly set to be either universal, global or local, but has been previously defined, the variable scope is not changed.
-# If a variable is not explicitly set to be either universal, global or local and has never before been defined, the variable will be local to the currently executing functions. If no function is executing, the variable will be global.
There may be many variables with the same name, but different scopes.
