Calling a exe from another exe?

Hi all,

Assuming exe1 and exe2 are executable files compiled by
Blitz3D:

(1) Is it possible to call a exe2 from another exe1?
After exe2 is finished, it returns controls to exe1 and continue running. (similar to procedure/function)

(2)If possible, could we return some results from exe2
to exe1 ?

Thanks in advance.
