ARRAYP command


>>-ARRAYP--+-----------------+---------------------------------><
           '-dim--+--------+-'   
                  '-length-'

where:

dim: The decimal number of pointers in the array.
length: The hexadecimal length of each element pointed to by the pointer. The default for length is whatever fits on one line in the current display format.

Many control blocks are mainly list of pointers. For example, the Communications Vector Table (CVT) is an MVS™ control block that points to many other control blocks. The ARRAYP command shows the data pointed to by the pointers in a control block. Use the ARRAYP command when you are looking for the offset of a pointer to a particular storage location.

For example, to see what is pointed to by the elements of CVT, enter ISRDDN and type

B 10.?
ARRAYP

You see a screen similar to Figure 1.

In the ARRAYP format display, the offsets on the left are the offsets within the array of pointers followed by the pointer itself. This is followed by the data to which the pointer refers.
