// split at five byte boundaries array fivers = array_sscanf(str, "%{%5s%}");
What about
array fivers = str/5;
then? Is that considered uggly?

second: not sure if pasting from hilfe is a good idea. probably not, because, then you can't cut the examples and paste them for your own use...
i was however quite excited to see a few examples that look a lot nicer and compact in pike compared to perl :-)
Accessing Substrings //------------------------------ string str, value; int offset, count; value = str[offset..offset+count]; value = str[offset..];
string newstring, newtail; str = str[..offset-1]+newstring+str[offset+count..]; str = str[..offset-1]+newtail;
//------------------------------ // get a 5-byte string, skip 3, then grab 2 8-byte strings, then the rest string leading, s1, s2, trailing; [leading, s1, s2, trailing] = array_sscanf(str, "%5s%*3s%8s%8s%s");
// split at five byte boundaries array fivers = array_sscanf(str, "%{%5s%}");
// chop string into individual characters array chars = str/"";
