Data commands and errors on a cluster line

[roger32909 at bellsouth.net]

OpenVMS V8.2  PH (7.10.G1)

 Have several screens with a DETAIL file cluster of records occurring 6 times.
There are nine fields on a line.  When the prompt is at the first record in the line, if a user wishes to
return to action, the user enters // and the prompt returns nicely to the action field.

However, when the user enters data in the subsequent fields that triggers an error (usually a duplicate key error), there is currently no way to gracefully exit that cluster line.  To be sure, the PF4 key will return the prompt to Action, but there may be dozens of lines above that will be lost.

Anyone know of a command or technique to return to action from say line 6 without losing first five lines of data?
