This is an insightful observation. Nice one, Pete!
My stock method (and presumably the method you allude to above) is...
repeat for each line L in tVar
add 1 to x
if <data condition on L> then put "" into line x of tVar
end repeat
filter tVar without empty
Both methods operate on a single data set and avoid putting the output into
a second variable which, for large datasets, involve an unnecessary memory
overhead..
