Examples of the AMP parameter

Example 1

//VSAMDS1  DD  DSNAME=DSM.CLASS,DISP=SHR,AMP=('BUFSP=200,BUFND=2',
//           'BUFNI=3,STRNO=4,SYNAD=ERROR')

In this example, the DD statement defines the size of the user area for data and index buffers, specifies the number of data and index buffers, specifies the number of requests that require concurrent data set positioning, and specifies an error exit routine named ERROR.

Example 2

//VSAMDS2  DD  DSNAME=DSM.CLASS,DISP=SHR,AMP=('BUFSP=23456,BUFND=5',
//           'BUFNI=10,STRNO=6,SYNAD=ERROR2,CROPS=NCK',
//           'TRACE=(PARM1=F00203000010,KEY=ABCDEF)')

In this example, the DD statement defines the values for BUFSP, BUFNI, STRNO, and SYNAD, as in the previous example. It also specifies that a data set post-checkpoint modification test is not to be performed when restarting at a checkpoint and that GTF is to provide a trace of specified data areas.
