Re: Loading an array from multiple fields in a record

[Charles Wilt <charles.wilt@xxxxxxxxx>]

Here's my preferred method...

d myDS   ds
d  FieldData
d    Field01               Overlay(FieldData)
d    Field02               Overlay(FieldData:*NEXT)
d    Field03               Overlay(FieldData:*NEXT)
d    Field04               Overlay(FieldData:*NEXT)
<...>
d  FieldArray             Overlay(FieldData) Dim(24)
d                              like(Field01)

You don't need technically need the FieldData grouping field, but I
agree with Jon that it makes things clearer.
