Re: File Encapsulation Quandary

I'd argue that once you move up to more complex data especially from
more than one file you've gone beyond the simple "file encapsulation"
to the "business object encapsulation" Scott, myself and others
prefer. :)


Actually, when given the opportunity, I'll use both levels of
abstraction. I'd encapsulate file i/o in protected procedures (ie.
useable only from within the *SRVPGM) The publicly accessible
procedures would provide the business object/methods.

Even in those instances, my file i/o routines are often more than just
simple getters/setters; they provide a named function for example
InvMstr_ChangeLocation() updates the location field of the Inventory
Master file and is called by various Inventory_MoveXxxx() type
functions.
