For a different issue that I have already posted about I started poking around the expression wiki to see what I could find out about proper syntax for expressions when I came across a new expression to me.
Range looks interesting can I do this with it ?
if(iSrange(left([filename],3),0-999),yes it is,no it's not)
What happens if the first 3 characters of a file name is abc ?
My mp3 player does not cue by track# only by file name and some of my track's have the track number all ready and some don't.
the above expression could really help if it works properly.
