ASMA301W

Prior active USING on statement number nnnnnn overridden
by this USING
Explanation
The USING instruction specifies the same base address as a previous
USING instruction at statement number nnnnnn, and the base
register specified is higher-numbered than the previous base register.

System action
The assembler uses the higher-numbered base register for address
resolution of symbolic addresses within the USING range.

Programmer response
Check your USING statements to ensure that you have specified the
correct base address and base register and that you have not omitted
a needed DROP statement for the previous base register. You can suppress
this message by reducing the value specified in the WARN suboption
of the USING option by 1.
