Horses for courses! most of my programming would be much harder to do if I had to put up with wosname from the compiler. So I love pointers and arrays and not having to touch the hardware through thick felt gloves, but I conceed that in the middle of encrypted fpos transactions you proddly (probably :-) don't want to worry about them. if O'caml works for you <yay>, but don't presume that C is a bad option for me! I know how to write bullet-proof C. eg SPTA (NSW) train transponder system 5000 lines very complex C (digital filtering etc) several 1000 transponders every train every day 10 years BUGS Found: 0 QED James James -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
