qualifying datanames

We're a couple of COBOL programmers converting RPG code. We standardized our
datanames because we thought that was 'good'. We are used to qualifying
datanames in COBOL and didn't think what it would do to the RPG code.

Is there a way of qualifying names in RPG IV? I think the list has already
answered this as a 'no' but I wanted to double check.

Working on the assumption that you can't, what's the best way to make sure
that we are getting the value of variable that we expect? Should we save the
value and use the new named variable? We don't have the time or the
expertise to change the flow of the chains/reads.

Should we rename the fields so that they are unique in each file? We hate to
do this because we took great pains to try to cut down the size of the field
reference file but would like to know if this is the preferred method.

For example, the field containing the social security number, should it be
named SSNMED in the medical plan file, SSNDEN in the dental plan file, etc.?

Please advise. Appreciate much.

Thanks.
