After you identify an individual segment of interest, choose the Traceback of Allocation menu item in the Memory Map pop-up menu. Traceback information can help you understand why your segment was created. Viewing traceback is also a preliminary step to displaying application code. Traceback information consists of a partial segment definition (a segment definition without a cursor address) and the list of elements on the callstack at the moment your segment was created. The element naming convention is: image name\module name\routine name\line number For example: traceback: 8:000BA800+00065C00=00120400 DECC$SHR (Image) 00066EDE DBG$HA_KERNEL 00005864 CRL$MAIN_DB\CRL_LIBRARY\crl__initialize_libraries\%LINE 5592
