A Guide for the SAS/C Compiler Consultant, Release 6.50

Usage Notes Tape and Contents

The Usage Notes and zaps for SAS/C software products can be obtained for MVS and VM. They are all contained on a magnetic tape with standard labels for all files except those created on VM via VMFPLC2, which creates unlabeled tapes. The tape is either a 1600 BPI, a 6250 BPI, or a 3480 cartridge, depending on your installation requirements. The tape volume serial numbers are of the format UCyymm, where yy is the year and mm is the month. For example, the Usage Notes tape for August, 1997, has the volume serial UC9708.

Zaps are contained in an MVS PDS, VM MACLIB, or individual files. All zaps should be applied using the APPLYZAP utility for both MVS and VM; however, it is possible to use either OBJZAP or IBM AMASPZAP on MVS and the VM ZAP utility on VM, if necessary.

The members of the zap library consist of individual zaps and zap indices. A zap index contains a list of the zaps that are applicable to a specific release (such as 6.50) and in a specific maintenance category (such as REQUIRED). The names of these index members are of the form $rrrxxxx, where rrr are the digits of release number and xxxx are the first four characters of the zap category. For example, an index of all the REQUIRED zaps for Release 6.50 is contained in the member $650REQU. The maintenance categories for zaps are as follows:

REQUIRED: corrects severe problems with incorrect execution, code generation, and so on. This zap should be applied by all sites that license the specified product on the specified operating system.
RECOMMENDED: can be applied without adverse effects at the discretion of the site.
SPECIAL CONSIDERATION: is only for certain situations, or requires special instructions to be applied. This zap requires that you read the corresponding Usage Note before deciding whether to apply it. You should not apply it unless you have encountered the specific situation it describes.
REMOVE: was found to cause problems and should be removed from your system. You should read the corresponding Usage Note for details. Please note that a zap marked REMOVE should only be removed if it has previously been applied to your system.
