Cheers for your help. I decided to try mandrake 10 the other day, got bored of Debian Stable. Mainly to try out gcc3.3 and kernel2.6 (too long to download on 56k) So I've now discovered how gcc interprets 'or' as '||' which I feel quite annoyed and let down by! I did n't realise what you meant. I've also discovered the other missing using namespace std's. (I thought I could get away with putting them in files which were included by others.) I'll get wcnt compiling with gcc3.3 and just put the whole thing up with some new examples. I've got some examples with 10 waveforms (coo!) and some with 20 (a world record for wcnt!) which would sound pretty good if it were not for artifacts: bummer. expect: withinish thish weekishn || next. ~(sirromseventyfive)~ _________________________________________________________________ It's fast, it's easy and it's free.
