Peter,

Perhaps we are talkng at cross purposes. I have been talking of table buffered scenarios, and I think you are using no buffering, hence your concern about my references to using tableupdate() to commit the data.

I think, though that the underlying issues are much the same.

From one of your other posts, where you describe the current status of your problems, I am a little confused about your references to blocks and records. My perception is that the 'block' which is added is a record of the proper length, but you have me thinking of blocks in terms of hexedit. I am not at all sure I understand how you are desribing the problem record in relation to the previous record, or to the end of file in terms of the byte positions.

I have noticed that the browse does not always disclose a problem, particularly at the end of a record which is 'short'. It effectively finds an empty field, or reports the content it does find.
