These no longer work in v6.2 and v6.3:
:put [:len [/ip route find !routing-mark]]
:put [:len [/interface find !comment]]
The alternative syntax suggested in http://forum.mikrotik.com/viewtopic.php?f=2&t=75894, with parentheses around !routing-mark and !comment, always returns nothing (len=zero).
Is this a bug or am I missing something?
Thanks for your help...
