Reliable indicator of AMODE in F7SA chain

When using Metal C, calling an ASCmode=AR function creates an ambiguous F7SA save area (in the DSA chain). The AMODE is switched BEFORE the call (BASR) is executed, and restored AFTER the return, so the AMODE of the caller (and therefore the DSAUSER offset in the caller DSA) cannot be reliably determined.

    We have investigated this RFE and we do not see a good way to support this requirement. As a result, this RFE is being rejected.
