Re: DDS arrays

["Peter Dow" <pcdow@xxxxxxxxx>]

One solution is to use input specs to rename the external fields as array
elements:

ICODEFL    (must be the format name, not the file name)
I        D61        D6(1)
I        D62        D6(2)
.
.
.
I        D66        D6(6)

Note that you do not specify from-to positions, just the names.
