filter

[Bernard Devlin]

put "one" & cr & "two" & cr & "owl" into tList

filter tList with "o*"

gives you

owl
one

Filtering that 2 line list with

filter tList with "t*"

will give you an empty list.  The first filter removed anything that
would match the 2nd filter, therefore the list is empty.
