Yes. The 'chop' call is not evaluated inside the quoted expression. There are two ways to handle it: 1. If the string is constant, you can use a read macro (match '(@A ~(chop "CITY") @B) ... 2. Otherwise you must build the pattern at runtime (match (append '(@A) (chop Varstring) '(@B)) ... ♪♫ Alex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
