EXECIO does not benefit from compiling the program. Someone has found that it even loses on compilation (although not much). Probably because of the overhead of creating and filling the stem variables. (NOTE that EXECIO is an external functionality!) FWIW, you could sometimes get better performance by using the stack instead of a stem when using EXECIO. I have no experience of stream on MVS.
