Special Dates

CA Disk treats Julian dates 99365, 99366 and 99999 as never scratch dates. That is, data sets whose ARCHVOLS or DSNINDEX records use these dates as expiration dates will not be deleted automatically as expired by the CA Disk function IXMAINT. In addition, if sysparm UNCATDEL defaults to a value of N, CA Disk treats DSNINDEX records with an expiration date of 99000 as never scratch.

If you specify sysparm UNCATDEL with a value of Y, CA Disk treats Julian date 99000 as a catalog control date. That is, data sets whose DSNINDEX record has an expiration date of 99000 will be deleted automatically by the CA Disk function IXMAINT when the data set becomes uncataloged.
