and a second array holds their lengths.
function p(stuff) {
print("<<<" + stuff + ">>>");
}
var mystring = " cats , trees, houses, bikes ";
if(@Length(@Trim(mystring)) == 0) { // Make sure string is not empty
p("No data");
return;
}
var mylist = new Array();
while(@Contains(mystring, ",") == @True()) {
mylist.push(@Trim(@Left(mystring, ",")));
mystring = @Trim(@Right(mystring, ","));
}
mylist.push(@Trim(mystring));
var mylistlen = @Length(mylist); // Create array with token lengths
for(var i = 0; i < mylist.length; i++) {
p(mylist[i] + " " + mylistlen[i]);
}
