When you want to have users select fields, which is what i guess, there are
some approaches:

- you know the file (or whatever the datafields holds) at program creation
time, then it's a select group like

C         SELECT
C         WHEN   FIELD = 'STATUS'
C         EVAL     VALUE = STATUS
C         WHEN   FIELD = 'BALANCE'
C         EVAL      VALUE = %EDITC(BALANCE:'J')
...and so on...

- you do not know the file at program creation time. Then you have to use
DSPFFD, or for performance's sake, the QUSLFLD (hope i remembered the name
correctly) API and read the file program desribed and SUBSTR your values out
of the record from the positions retrieved with the API. Quite a job,
especially when you have to deal lwith packed, binary, ... field types. Char
is easy... :-)
