Dealing with objects with tag

[khalil]

This will add 100 to the last group address part:

Code:

addr = event.dst:gsub('%d+$', function(a)
  return tonumber(a) + 100
end)
log(addr)

Thanks Admin
I think it will be easy for me to get only the last group address part as number, because its not the same pattern.

Also what is function(a)?

BR,
