SL3: Source String
SL2: Target for match (text to be replaced)
SL1: Replacement text

It's my understanding that:

SL3 would be my CSV file
SL2 would be the ■ (linefeed) character
SL1 would be " " (whitespace)

\<<
OVER SIZE @ get length of target string
\-> targ new len @ assign locals
\<<

I don't understand your use of OVER. Wouldn't there be only one object on the stack? Also, you declare 3 local variables, but there would only be 2 objects on the stack.

Thanks again for your help!
