First, you are on the wrong forum: Processing Implementations is for "Questions about Processing in Ruby, Python, JavaScript, ActionScript, Scala, etc. " while you seem to use good old Processing (still at 0135? that's old already... Smiley)

Second, well, it means that lst is an array with only one entry. Since it comes from a split, I suppose it means your line 'dat' has no comma inside. Do a println before the split to ensure that.

There is no correction, it depends on your input data.
You do:
String dat = lineshour[i];
String lst[] = split(dat,',');
replace with:
String dat = lineshour[i];
println(dat);
String lst[] = split(dat,',');
and see if there are commas inside the displayed line. If not, you found your problem.
