Examples of changing unit attribute table default values z/OS Language Environment Customization SA38-0685-00 |

The following examples show how you can modify the IBM-supplied defaults for your own environment. You can alter instructions by typing over existing data, or you can add more VSF2UNIT and VSF2DCB macro instructions. Example 1In this example, we have specified device name SYSSQ for dynamically allocated data sets and assigned a unique set of DCB attributes to units 1 through 4. The DCB Information for both sequential formatted and unformatted files written on these units is indicated in the first VSF2DCB macro instruction ("USERDCB") shown in Figure 1. Figure 1. Modified IBM-supplied
macro instructions
Note: The above format is given for readability purposes. Remember
to add the necessary continuation flags in column 72, and to begin
continued lines in column 16.
VSF2UAT, VSF2UNIT, and VSF2DCB must all be coded, in that order, followed by the VSF2UAT TYPE=FINAL statement. Example 2If you want to change the unit numbers of the standard input unit, the error message unit, the print unit, and the punch unit, to 1, 2, 3, 4, respectively, modify the IBM-supplied macros as shown in Figure 2.
