ESO tapes

As an IBM® customer, you may periodically receive a customized ESO tape based on your IBM software distribution profile. This tape has the PTFs, HOLDDATA, ++ASSIGN statements, and UCLIN data needed to bring your system up to the current service level.

Service levels are identified according to when they were available correctively. For example:

Service level	When available correctively
0708	August 2007
0801	January 2008
0811	November 2008

The ESO tape is a nonlabeled (NL) tape, with files arranged as shown in Table 1.
