No getting any trace stack dump of exception occurred in program calls. Pls help.

Using OpenVMS 8.3 version Itegrity Server.

I have Server program in C, here we are setting error handler. Now this program calls some FORTRAN programs, here main calling fortran program again set error handler.

Some Exceptional conditions are occurring in FORTRAN module which results in call transfer to Fortran error handler, here in debug mode I am able to get call trace where exception generated however once call transferred to C error handler I am not getting any call trace from where this exception is generated. Even I have checked it by commenting the error handler establish at FORTRAN end. So, during execution mode I am not at all getting any trace back dump.

To get the trace back dump during execution mode at Fortran end I used following commands but no result.

CMND='SHOW CALLS;GO;EXIT' --->CALL LIB$SIGNAL(SS$_DEBUG,1,CMND)

CALL LIB$SIGNAL ( %VAL(SS$_ACCVIO) )

CALL SYS$PUTMSG (SIGARGS,0,0,0)

CALL SYS$UNWIND(MECHARGS(5),)

===============================================

I want trace back dump as shown below but nothing getting except out generated msg

Problem get resolved. As, I have mentioned in problem that we have 2 different error handler and I was trying to catch trace back stack dump during exception handler in Fortran but in fact call was getting transferred to C error handler whenever any of above written commands were getting executed. I got the the traceback dump in C error handler using below command -

CMND='SHOW CALLS;GO;EXIT' --->CALL LIB$SIGNAL(SS$_DEBUG,1,CMND)
