Thanks for the reference Bernie. I went there, downloaded the file com.zip, and it reads: In principle, a COM file is just loaded at offset 100h in the segment and then executed. That's exactly what I was trying to say - sorry if I didn't convey my thoughts very well. DOS never loads any executable at 0000:0100H - that's where the BIOS maintains several system variables such as basic system peripheral information, system time, and the keyboard buffer, etc. DOS picks a convenient segment (any segment anywhere in memory) and loads the COM file at offset 100H *within* that segment (xxxx:0100H) - not at 0000:0100H. Hope this helps...

Mr Otto: You had better go to www.wotsit.org and search and download the description for COM files and read it.
