Syntax<br />

DLEXCPCOUNT | NODLEXCPCOUNT<br />

DLEXCPCOUNT<br />

reports the EXCPs (Execute Channel Program calls) that <strong>SAS</strong> per<strong>for</strong>ms on direct<br />

access bound libraries and the number of blocks that were transferred in these<br />

EXCPs.<br />

NODLEXCPCOUNT<br />

does not report the number of EXCPs that <strong>SAS</strong> per<strong>for</strong>ms on direct access bound<br />

libraries and the number of blocks that were transferred in these EXCPs.<br />

Details<br />

Specifying DLEXCPCOUNT causes <strong>SAS</strong> to generate a message that reports the number<br />

of blocks processed and the corresponding number of EXCPs issued to each <strong>SAS</strong> data<br />

library since the library was opened. This message is produced when the library is<br />

closed. The message is written to the z/<strong>OS</strong> system log as a WTO message. The message<br />

is also written to the <strong>SAS</strong> log except when the library is closed during termination of<br />

the <strong>SAS</strong> session. The message text output is in this <strong>for</strong>m:<br />

<strong>SAS</strong> processed blocks and per<strong>for</strong>med EXCPs on<br />

library ‘data set name’<br />

Note: A library is opened the first time it is referenced in a <strong>SAS</strong> session. It is closed<br />

when the last libref that is assigned to the library is cleared. If the library is still open<br />

at the end of a <strong>SAS</strong> session, the library is closed as part of <strong>SAS</strong> termination. R<br />

The values of BUFSIZE= and BUFNO=, specified as data set options or <strong>SAS</strong> system<br />

options, have a direct effect on the number of EXCPs per<strong>for</strong>med. Increasing the value of<br />

BUFSIZE= increases page size and reduces the number of EXCPs required. Specifying<br />

a larger value <strong>for</strong> BUFNO= causes more blocks to be read with a single EXCP under<br />

certain circumstances, thus reducing the total EXCP count.
