POPL plname
POPL plnamelist

Prints the contents of the named property lists(s) to the current write stream. POPL abbreviates PO PLLIST.

POPL treats all non-existent property lists as empty property lists. This is consistent with how GPROP behaves when asked to get a non-existent property.

PPROP "plist1 "p1 1
POPL [plist1 plist2]
Pprop "plist1 "p1 1
