Hi Vache
Here is one short way to do what you want, by making use of a second block.
>> new-data: []
== []
>> foreach item table-data [if item <> "" [append new-data item]]
== ["CREAF" "Nasdaq-NM" "$" "14.3125" "0.4375" "3.15%" "28,800" "CSCO"
"Nasdaq-NM" "$
" "52.6875" "2.125" "4.2%" "21,082,300" "DELL"...
There are problems with using remove and other series mutators in loops
because it is changing the length of the series and the position of the
current index of the series while the loop is executing.
The test in the loop could also be written in other ways:
if (length? item) > 0
if not empty? item
