When copying from a PACKED or ZONED to a DATE, the assumed form is the form the copy will expect<br />
the data to be in. When copying from DATE to a PACKED or ZONED field the assumed form is the form<br />
copy will attempt to convert the data to.<br />
These conversions are already supported.<br />
When converting/copying a ZONED field (with no DATFMT) from/to a DATE<br />
field (FMTOPT(*MAP) that is specified, the corresponding from and to-field names<br />
matching the system assumes the ZONED field is to be in a form determined from<br />
the current job DATFMT value and the ZONED field length (see table for<br />
specifics).<br />
Similarly, when converting/copying a PACKED field (with no DATFMT) from/to<br />
DATE field (FMTOPT(*MAP) specified and the corresponding from and to-field<br />
names match, the system assumes the PACKED field is to be in a form determined<br />
from the current job DATFMT value and the PACKED field length (again, see table<br />
for specifics).<br />
For the new DATFMTs that have a ’century guard digit’, the system allows the<br />
values 0-9. 0 is for the year range 1900 through 1999, 1 is for 2000 through 2099, 2<br />
is for 210 through 2199, and so forth, up to 9 for 2800 through 2899. The formats<br />
allowing ’century guard digit’ are *CDMY, *CMDY, and *CYMD.<br />
For the new DATFMTs that have no ’day’ portion, *MY, *YM, *MYY, and *YYM,<br />
the day is assumed to be the first day of the month. For conversions to one of<br />
these DATFMTs from a DATFMT that has a ’day’ portion, the ’day’ value is<br />
removed.<br />
For conversions from the no ’day’ DATFMT to a DATFMT having a day portion,<br />
the ’day’ value becomes the first day of the month. For example, the *YYMD value<br />
’19971231’ becomes ’199712’ when converted to *YYM. When converted back,<br />
’199712’ becomes ’19971201’.<br />
