I'm having a small problem understanding the CESD data the linkage
editor generates for a load module, in particular, bit 1 of the
flag byte (byte 13, starting from 1) in the 16 byte field. In my
version of MVS/370 Link Editor Logic this byte is described as
xxxxRRAA, where xxxx is "not used", and RRAA contain the RSECT,
RMODE and AMODE bits. The Assembler H V.2 Programming Guide
likewise documents only the RMODE and AMODE bits. However, many
CESD entries of my modules (when linked by the MVS/XA linkage
editor) contain a "1" as the second "x" bit in this flag. Does
anybody know what it means?

Thanks,

Shaul Wallach
