Hi,

I have a simple, general question regarding a real small issue that bothers me:

I'm printing a list of elements on the fly, so I don't have prior knowledge about the number of printed elements. I want a simple format where the elements are separated by a comma (elem1, elem2...) or something similar. Now, if I use a simple loop like:

while(elements to check) {
  if (elem should be printed) {
     print elem . ","
  }
}

I get a comma after the last element...

I know this sounds quite stupid, but is there a way to handle this?
