UTY6657 Overlappings in variable length fields are not allowed with FORMAT UNFORMAT.
Explanation:
With format unformat data, if explicit positioning is used with an overlap for the first variable-length field, then TPump will terminate.

Remedy:
Either remove the first variable length field which is explicitly positioning and overlapping, or change the input data format to either FASTLOAD or BINARY. Then resubmit the program.
