We use Transact/iX and it's debugger and not COBOL, but I believe the techniques must be similar. We hook both the network and a serial line from the HP3000 to a PC and with a windows terminal emulator, we can then have a networked session and a serial session (2 windows). Running from the networked connection, the serial connection can then be considered a dumb terminal and used to redirect displays or the VPLUS screens etc. Costas Anastassiades Information Systems and Internal Communications Dept, INTRACOM SA Athens-Greece ---------- From: Your Name[SMTP:[log in to unmask]] To: [log in to unmask] Subject: How to debug VPLUS program without dumb terminal? <<File: ATT00001.txt>> I used to debug a COBOL program with VPLUS screens with a dumb terminal. But these day there is no dumb terminal anymore. I asked many people abo ut it, and nobody was able to answer the question. Any guru on the net c an answer this question?
