Here is code that walks the ODP chain. Only the traditional ODPs
from the QDM* routines are here. The new ODPs from IFS are chained
elsewhere, in Unicode.
dcl sysptr ?QDMCQ baspco pos(H"21");
dcl mspptr ?Walk;
dcl dd Forward bas(?Walk) pos(1) bin(4);
dcl sysptr ?ODP bas(?Walk) pos(H"31");
dcl mspptr ?Space;
setsppfp ?Walk, ?QDMCQ; -- point to data mgmt queue
setsppo ?Walk, H"98"; -- point to shared header
cmpnv(b) Forward, -1 / neq(AA); -- jump if a shared exists
setsppo ?Walk, H"A0"; -- point to non-shared header
AA: cmpnv(b) Forward, -1 / EQ(BB); -- exit loop if end of chain
setsppo ?Walk, Forward; -- point to next entry
setsppfp ?Space, ?ODP; -- point into an ODP space
b AA; -- repeat until end of chain
