Vini, if you just want to test whether a value has been specified or not,
you could have a data structure initialized to the database default values
(use INZ(*EXTDFT) if you're on V4R4).  Then you would just compare pos 1-5
of the record with pos 1-5 of the data structure.

If you have more complex checks to make, you could have a separate
subprocedure for each type of field.  Pass in the address of the
record, and then within the subprocedure, you can define the record
exactly the way you want.  I think Buck Calabro already suggested something
like this.

P checkType1       b                 export
D checkType1       pi
D   pRecord                      *   value

D record           ds                based(pRecord)
D   idnum                  1    5p 0
D   dudate                35   44d
 ...

P checkType2       b                 export
D checkType2       pi
D   pRecord                      *   value

D record           ds                based(pRecord)
D   name                   1   75a
