I would say that there is no such thing as a cross-memory parameter. But there
is AR-qualified data (which might be within a data space or an address space).
LAE is already used.
Services that support AR-qualified parameters, when appropriate, will use the
AR of an identified GR and will use LAE for an RS-type or RX-type specification
when the ALET is needed.
Here's a non-working (the regs and fields are not initialized) but
syntactically correct example
TEST CSECT
SYSSTATE ASCENV=AR,ARCHLVL=OSREL,OSREL=SYSSTATE
USING @DATA,12
CSVAPF REQUEST=LIST,ANSAREA=(2),ANSLEN=(3)
CSVAPF REQUEST=LIST,ANSAREA=AA,ANSLEN=AL
@DATA DS 0D
AA DS D
AL DS F
END
Assemble this and look through the expansions for things like LAE and STAM.
