Do try to keep up, please. :-) According to Wikipedia, dbx's original developer was Mark Linton at the University of California, Berkeley. He wrote dbx in the period 1981 to 1984, and then it percolated through the BSD ecosystem. TSO TEST first appeared no later than 1972, so dbx is about a decade younger. Whether dbx is more "modern" is a separate question. :-) Another debugger, IBM z/OS Debugger, is the successor to the IBM Integrated Debugger and IBM Debug Tool. There are lots of IBM software products that include IBM z/OS Debugger -- 6 if I'm counting correctly -- so it's possible or even likely you already have a license. Of course if you don't have a license it's possible to acquire one. - - - - - - - - - - Timothy Sipples I.T.
