Absolutely!  Excellent suggestion, although not all 400's have the SQL
development kit.

Although SQL is itself a welcome abstraction from the physical file layout,
putting the SQL inside an "update" procedure, will allow you to quickly
change from "native" to SQL without impacting the calling code.  Using
procedures can let you experiment with the various trade-offs (run time cost
vs development cost vs maintenance cost) more readily than with inline code.
This helps to separate the business problem from the specific implementation
as well as creating the optimum implementation for your environment.
