Dick's solution set up the initial array by putting "true" into each  
element, so I think his syntax is perfectly correct :-)

>   repeat for each line tSymbol in field 2

It was a great solution. I thought that putting the field data into  
variables first might speed things up, but it didn't, so the "repeat  
for each" loops must grab the complete set of data before they start.  
Very efficient.
