Data type of "Open"?

["Brad Stone" <brad@xxxxxxxxxxxx>]

I'm on V5R2 and working with a customer on V5R3.

The application in question creates a PF and does a CPYSPLF
to that file.  On V5R2 and previous the field used was of
data type "Char".

On V5R3 it's now showing as a data type of "Open" which is
messing up their SQL statements that they're doing on the
file.

The command being used is:

CRTPF      FILE(QTEMP/TEMPFILE) RCDLEN(134) +
           MBR(*FILE) IGCDTA(*YES) +
           SHARE(*NO) +
           LVLCHK(*NO)

IGCDATA used to be set to *YES or *NO depending on if the
spooled file was DBCS or not, and on V5R3 it seems that
they all are, so this is the only difference I can see.

Any ideas?  What is a data type of "Open"?
