RE: stand alone modules (no service program) and handling file I/ O

I understand about the service programs especially for 'common modules' .
For this purpose these modules are used only for a conversion program that
is run one time only for new clients. They wont be in use by any other
programs. I did read abit about the %Open syntax. How far back can I compile
programs that use the %Open ?
Currently I have to compile at v4r4. In any case, Ill scour online for the
%open info.
Thanks alot.
