I ask because I wrote a bunch of tiny CP/M programms, in assembler because I was using every trick I could to make them small. I believe the ones I had on every floppy were: ls cp mv rm and each one of those I made fit in either one or two 512 byte sectors because they weren't memory resident, it had to spin up the floppy and read them in each time I ran them. So I wanted them small for two reasons: speed of reading them in and not taking up precious space on the floppy. I had a utils floppy that had larger programs on it, like grep, my quicknet terminal emulator/file transfer tool (I wish I had saved the source to that). my CP/M machine was an Okidata with a color(!) monitor and a built in printer with two floppies so I could do work on one floppy and get the utils on the other. Hmm, wonder if there is picture of that machine on the net? Of course there is: http://www.old-computers.com/museum/computer.asp?c=94 So Clem, did Leor do any utilities that I didn't know about or are you talking about his not so standard C library? --lm
