I've only used it with C and Pascal, however; I assume it would work as well in Fortran, but I'm not so sure about COBOL. SPT/3000 provides breakdowns of the time spent in selected system intrinsics as well as breakdowns to the instruction level of the time spent in application code. It's a statistical sampling system rather than an instrumentation system, so there can be some inaccuracies when dealing with synchronous events. However, this shouldn't be a problem for most application software. It has certainly proved its worth here: in one case, some "harmless" debugging code left in a production application "just in case" turned out to be responsible for 15% of the application's total CPU time. -- Bruce -------------------------------------------------------------------------- Bruce Toback Tel: (602) 996-8601| My candle burns at both ends; OPT, Inc.
