synchronization
.... ..1. SHPINIT X'02' SHPINIT CVM was initialized
at least once
.... ...1 SHPCVMA X'01' SHPCVMA The CVM is active
In an SSI environment CP is the
CVM so it is always active, thus
in the main SHPBK this bit is
always set. In an associated
SHPBK this bit is set if we have
a socket open with that member.

0040 64 Bitstring 1 SHPISFRI S*9 CSE level code, if known
defined for the other. In an SSI
environment SHPISFRI is intended
to be a counter not a bitmap and
it should be tested with CLI not
TM.

: SHPISFRI is combined with
SHPSSTAT (below) so the

defined for the other.
1... .... SHPNSHRS X'80' SHPNSHRS Cross system

005C 92 Signed 4 SHPSOCK Socket identifier In the main
system's SHPBK this socket handle
