Examples of the DATACLAS parameter
Example 1
//SMSDS1 DD DSNAME=MYDS1.PGM,DATACLAS=DCLAS01,DISP=(NEW,KEEP)
In the example, the attributes in the data class named DCLAS01 are used by SMS to handle the data set. Note that installation-written ACS routines may select a management class and storage class and can override the specified data class.
Example 2
//SMSDS2 DD DSNAME=MYDS2.PGM,DATACLAS=DCLAS02,DISP=(NEW,KEEP),
// LRECL=256,EXPDT=1996/033
In the example, the logical record length of 256 and the expiration date of February 2, 1996, override the corresponding attributes defined in the data class for the data set. Note that installation-written ACS routines may select a management class and storage class and can override the specified data class.
