The current PIN ($22) is the program CI.PUB.SYS. In DAT, we do a stack trace, but we
observe that the symbols for the program file are not part of the stack trace.
($22) nmdat > loadinfo
nm SYS NL.PUB.SYS SID = $a
cm SYS SL.PUB.SYS
($22) nmdat > xl ci.abuild00.official 74 ci.pub.sys
Preprocessing CI.ABUILD00.OFFICIAL, please wait ... Done
($22) nmdat > loadinfo
nm USER CI.PUB.SYS SID = $74
nm SYS NL.PUB.SYS SID = $a
cm SYS SL.PUB.SYS
($22) nmdat >
A quick check of our loaded files reveals that DAT does not know about the symbols for
CI.PUB.SYS. We now use the PSEUDOMAP command to open a local copy of the program file
from which symbol information can be gleaned. A final check of the loaded file information
shows that CI.PUB.SYS has successfully been added to the list.
Note that the stack trace code works because the unwind descriptors for CI.PUB.SYS
happen to be present in the dump. This is usually not the case (unless the file was loaded
as a "dumpworthy" file).
