Reblocking more than one data set at a time

If you upload a large number of files to z/OS® but do not want to separately enter the AFRREBLK command to reblock each data set, you can use ISPF to display the names of the data sets, and then enter AFRREBLK one time in the command section to reblock all the data sets.

For example, if you uploaded numerous AFP documents to the host, all with a third qualifier of UPLD, UPLD240, or UPLD300, go to ISPF 3.4 and specify a DSNAME LEVEL that corresponds to your uploaded data sets, such as:

In the command section of the listing, enter AFRREBLK to the left of the first data set you want to reblock and = to the left of any other data sets you want to reblock (see Figure 48).
