LookAt is an online facility that allows you to look up explanations for most messages you encounter, as well as for some system abends and codes. Using LookAt to find information is faster than a conventional search because in most cases LookAt goes directly to the message explanation.
You can access LookAt from the Internet at: http://www.ibm.com/eserver/zseries/zos/bkserv/lookat/
Alternatively, you can access LookAt from anywhere in z/OS® where you can access a TSO/E command line (for example, TSO/E prompt, ISPF, z/OS UNIX System Services running OMVS). You can also download code from the z/OS Collection (SK3T-4269) and the LookAt Web site that will allow you to access LookAt from a handheld computer (Palm Pilot VIIx suggested).
To use LookAt as a TSO/E command, you must have LookAt installed on your host system. You can obtain the LookAt code for TSO/E from a disk on your z/OS Collection (SK3T-4269) or from the News section on the LookAt Web site.
Some messages have information in more than one document. For those messages, LookAt displays a list of documents in which the message appears.
