First of all, split uses a regex and this is not searching for anything
other than empty strings... I think

or maybe I am dislexic

You might need a need the regex {^\d.*}
or [^0-9]

or better - don't use split and hunt for digits specifically and secure
your input code

Also, print out fdat and see what you are actually generating and don
t swim in dark holes :)
