FUNCTION with GLOBAL parameter

Description

If a function receives a parameter into a global variable, parameter will not be passed to a function. Instead, in function global value will be available.

Example code to demonstrate the bug.

global num
num = 3
print "square=";square(4)
wait

function square(num)
  print num
  square=num^2
end function

Prints

"3"
"square=9"

Expected behavior

"4"
"square=16"

You should be able to write that code, and it should print 16. When a parameter variable name is the same as a global name, it should be treated as a variable named scoped for that function.

Example code to work around the bug.
