Usage notes

The RENAME FIELD command changes the name of a field. The command is rejected if the old field name does not exist or if the new field name cannot be added to the file, either because it already exists or because there is not enough space. RENAME FIELD can be used to rename Ordered Index fields.

When it processes RENAME FIELD, Model 204 ends any update unit in progress and begins a non-backoutable update unit.

Restrictions on renaming:

• The RENAME FIELD command is prohibited for the DTSFN field in a file when the FOPT=X'10' is set. Attempting to do so results in the following message:

  M204.2727: CANT DELETE DTS FIELD WHEN FOPT=X'10' IS ON

• Renaming of OI chunk and OI chunk target fields is not allowed.
