Re: Force EOF in a Subfile

["Carel Teijgeler" <coteijgeler@xxxxxxxxx>]

Kurt,

I do not understand your question. 

Reading through a SFL and turning on SFLNXTCHG will make the changed records 
availble for the next READC. And this READC will start from the top of the SFL 
after each EXFMT. Reords not read the first time are still marked as changed.

Regards,
Carel Teijgeler
