Multiple labelled USINGs are often what I want and, IMHO, a lablled dependent USING would be appropriate for what the OP wants. Of course, he would also need to qualify the refereneces subject to that USING.

I think your dependent USING has its operands reversed. What you've done is not inherently wrong, but it's unlikely to be doing what you meant. You are telling the assembler that the first operand can be addressed using the address supplied by the second operand, e.g. in an ordinary USING you would typically have USING dsectname,Rn For a dependent USING, instead of specifying a register directly, you supply as the second operand a name that can already be resolved with an existing USING, and this must eventually lead to a register+offset. But you are supplying a name within WKAREA that will be resolved using R13 (as shown by the Active USINGs). And what is it that you are saying you will want resolved by this USING? It's a portion of your CSECT space starting at +2B94. Tony H.
