ZDCOR-Display Core

Use this command to display a variable amount of system virtual memory (SVM), also known as core memory.

Requirements and Restrictions

You must specify the IS parameter in a tightly coupled system when prefixing applies; for example, when you display storage in page 0 of an I-stream, or when you display the I-stream unique global areas.

Format




address
is a 1- to 8-digit (4-byte) hexadecimal system virtual memory (SVM) address.

bytes
is the hexadecimal number of bytes to display from X'01'-X'FFF'.
Note:
If you specify a value of X'00' bytes, the default number of bytes is displayed.

Is-xx
specifies the I-stream that this change affects, where xx is a decimal number from 1 to 16.

Instr
displays the data in disassembled format rather than hexadecimal format.
Note:
You can display only as many as X'400' bytes at a time in disassembled format.
