Sorry for the off-topic question but does anyone who is sco-knowledgable know where stdio.h is on sco? I can't find the #$#@%% thing and therefore can't compile anything. It's bothering me to no end b/c I need to compile the new sendmail but can't. I have gcc on and I have a lot of includes in /usr/include/ but I don't have a stdio.h any help. thanks again sorry for the off topic post later -sv
