1: Shows the number of the statement that contains the USING, DROP, PUSH USING, or POP USING instruction.
2: Indicates whether the instruction was a USING, DROP, PUSH, or POP instruction.
3: Shows the type of USING instruction. A USING instruction can be an ordinary USING, a labeled USING, a dependent USING, or a labeled dependent USING.
4: For ordinary and labeled USING instructions, this field indicates the base address specified in the USING. For dependent USING instructions, this field is prefixed with a plus sign (+) and indicates the hexadecimal offset of the address of the second operand from the base address specified in the corresponding ordinary USING.
5: Shows the range of the USING. For more information, see the description of the USING statement in the HLASM Language Reference.
6: For USING instructions, this field indicates the ESDID of the section specified on the USING statement.
7: Indicates the registers specified in USING instructions, and DROP instructions. There is a separate line in the USING map for each register specified in the instruction.
8: Shows the maximum displacement from the base register that the assembler calculated when resolving symbolic addresses into base-displacement form.

You can suppress this section of the listing by specifying the USING(NOMAP) assembler option, or the NOUSING assembler option.
