In the index CI, there are two kinds of pointer: vertical and horizontal pointer. The horizontal pointer point to the next same level index record.
So when start browse a KSDS file, the horizontal pointer is very efficient to find the next SSI for readnext command. But when use readprev command to read file in descending order, there isn't any pointer to point to the previous SSI in the index CI. So anyone know how readprev work? Return to the higher index level to find the previous SSI? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
