If physical paging is used, the limit of 500 applies to each physical page. A labelled DFLD which is not referenced by an MFLD in the MID or MOD does not count toward this limit. The DFLD limit is after any DO statement iterations.
There is a cumulative limit of 19,996 bytes for a pool area to store MID literals, MID default literals, MOD literals, DFLD literals and PF key data. If this limit is exceeded, MFSGEN error message MFSUT0L17 is issued. The lengths are cumulative and are the lengths of the literals plus six bytes of overhead for each literal. Some of the 19,996 bytes is used for labelled DFLD data so the actual maximum size is somewhat less.
| Keyword | Values | 3270 Display DFLD Description |
