Use this file- or record-level keyword to inform the remote program that control data is being sent.
This keyword has no parameters.
The CTLDTA keyword is ignored at run time when the EOS, RSPCONFIRM, or RQSWRT keyword is in effect. These keywords must have option indicators if they apply to a record for which CTLDTA applies. If an EOS, RSPCONFIRM, or RQSWRT keyword with no option indicator applies to a record for which CTLDTA applies, an error message is issued and the CTLDTA keyword is ignored at creation time.
You cannot specify CTLDTA with the TIMER keyword.
Option indicators are valid for this keyword.
The following example shows how to specify the CTLDTA keyword at the record level.
