Range of a dependent USING instruction HLASM Language Reference SC26-4940-06 |
|
The range of a dependent USING instruction (called the dependent USING range) is either the range as specified by the range end, or the range of the corresponding USING minus the offset of address within that range, whichever is the lesser. If the corresponding labeled or ordinary USING assigns more than one base register, the maximum dependent USING range is the composite USING range of the labeled or ordinary USING. If the dependent USING instruction specifies a supporting base
address that is within the range of more than one ordinary USING,
the assembler determines which base register to use during base-displacement
resolution as follows:
