Allow Subroutines To Access Variables/Parameters Defined At The Outer/Parent Level

Adriano dos Santos Fernandes

Tracker ticket: #4769

Subroutines can now read from and write to variables and parameters of the outer/parent routine.This does not apply to cursors: subroutines cannot access cursors of their parent.

Variables and parameters that are accessed by subroutines may have a small performance penalty (even in the main routine) when being read.
