[PD] if - empty list

[Dieter Untermieter]

hi

thanks for your hints - they have been very helpful

two new problems occured now:
- is there anything like a "if"-object in pd. i think that i used such a object in pd, but when i try to  create such a object pd tells me that there is no if object.
- and i am looking for a way to empty a list.

any hints again?

yours
