Accessing program variables across 4gl files in the same executable

Hi Is it possible to access program variables (i.e. variables declared before "main" dont confuse these with globals) across 2 or more 4gl programs within the same executable (.4ge file). Say for example I have one 4gl program containing the "main" and "end main" which in turn calls functions which are declared in another 4gl program. Can these 2 programs access a common set of variables (similiar to "extern" variables in "C") Thanks Manish
