There is no 'function scope'. 

There _is_ function scope.
Function scope is what labels are visible in.

There is 'block scope'. A variable defined in a block has the block scope. If it has the 'static' qualifier, it becomes persistent. 

Right.

labels ? goto ? Sorry, I don't code in assembly nor in BASIC anymore ;-)

I once asked an expert COBOL programmer, how to
declare local variables in COBOL, the reply was:
"what is a local variable?"
