Eliminating *MODULES with IMPORT and EXPORT parms and replacing them with Service Programs

When my company first started implementing ILE (before I came here), IIRC
IBM had not made their announcement discouraging the use of *MODULEs with
import and export parms (accessed via CALLB). The a few years later IBM
came out in favor of procedures and subprocs (callp, eval) in place of
callb to modules and at that time we stopped developing anything that
would use callb.

We still have a number of modules that do use import and export parms, and
I've been given the go ahead to have the staff start converting all
*modules (including those accessed via callb) into service programs.

My first thought was to simply change the call interface to the module to
make it a prototyped call, using the export fields as parameters.

Then in the programs that do the callb, change the import parms to place
them in a data structure using the same field names and attributes which
would be returned from the (new) service program.

Does anyone have any input regarding how best to go about doing this?

Thanks, Jerry
