Hi Rod, thank you for looking into this. I was so happy that I got it working (on my PC at least) that I did not follow your suggestion. When I run your code I see that it finds and prints the master environment block, i.e. the environment of command.com and that does not contain the absolute path to the running program I am looking for. >dosmemget(the_psp+0x16, 2, &the_psp); reads the psp of the parent process and that is command.com. I do not fully understand the loop but it exits with the psp of command.com and then reads the environment from there. I can check that with the "mem / d |more" command. Georg By the way this is the output of my program on my PC: E:\myprogs\djtest>mcb4 MCB:21B0 M PSP:8 Blocksize:1ED MCB:4090 M PSP:40A Blocksize:BA ENV:4CD Program:COMMAND MCB:4C40 M PSP:0 Blocksize:7 MCB:4CC0 M PSP:40A Blocksize:7D MCB:54A0 M PSP:54B Blocksize:87A ENV:D312 Program:DOSX MCB:DC50 M PSP:FB5 Blocksize:70 Path:E:\MYPROGS\DJTEST \MCB4.EXE MCB:E360 M PSP:E37 Blocksize:17D ENV:DC6 Program:KB16 MCB:FB40 M PSP:FB5 Blocksize:410 ENV:187 Program:MCB4 MCB:13C50 M PSP:0 Blocksize:F00 MCB:22C60 Z PSP:0 Blocksize:7D38 E:\myprogs\djtest>
