Even on embedded systems that isn't a lot. If he's that tight, it's going to be hard to even get a C program in there. And what's he going to do with something gets upgraded and needs more space?

Sorry to borther all of you, any info would be appreciated. Promise me this isn't your homework, and I'll show you maybe three printf() lines that will do as much as your output sample. Or, man 3 printf will get you started. And doing a web search on the string, printf formatting will get a lot more information. The query for this particular function shouldn't be hard either. The hardest part would be picking the approach. Do you want to ask for the address(es) interactively or do you want to take the addresses from the command line, or both? Shoot, if you don't mind postfix syntax, a nice FORTH interpreter (which I can suggest a few to you) will get you a good start. Some come in under 200k, including the full runtime execution environment. More complete FORTHs, like gforth, have an executable object around 130K in debian, and run easily in a 1M or so of run-time. And, again, the output you describe above is pretty straightforward formatting. -- Thanks Best Regrads! Nicol TAO (taozhijiang) Shenzhen, Guangdong Province, P.R. China 518055 Being Stronger!!!
