Thank you Simon. I certainly had omitted the 'p' in the RPG DS as the
default for standalone decimal fields is packed. But now I know better.

Are you sure the numeric fields are decimal in the RPG program? Your
description implies the packed decimal fields are contained in a data
structure. The default behaviour for RPG is to define numeric fields
in a data structure as zoned decimal (because the data structure is
presumed to be a big character field--historical reasons). Even if the
packed decimal field is defined elsewhere in the program (e.g.,
external file description) it will be remapped to zoned decimal by the
compiler.

If the above is a correct guess at the cause of your problem then
you'll either need to modify the RPG program and define the fields as
packed decimal in the data structure or redefine the C/C++ data
structure with char[] fields and convert them to decimal before use.

Simon Coulter.
