problem with counting words

[dunbarx at aol.com]

Pete. 


I think we are on the same page. Your code would have unpacked with each item as (returns just for clarity):


a
1,b
2,c
3


Probably your point is that this is not what was intended.


Your loop example is just like the sort of thing that started this. The intent was to be able to, given tData:


aaa,bbb,ccc#ddd#eee#fff,ggg,hhh


get item 2 to 3 delimited by "#" of item 3 of tData


would return:


ddd#eee

Yeah, I don't think word was considered during the discussion.

Multiple delimiters might be a good idea but it feels like you'd have to
know which delimiter had been encountered.  For example, if you had a
string like this:

a=1,b=2,c=3

and you wanted to unpack it with:

repeat for each item ritem delimited by "=,"
  doStuff
end repeat

You'd probably need to know which delimiter had been encountered to
distinguish between the left and right sides of the "=" character.

The main intent behind "delimited by" was to do away with having to keep
resetting the itemdelimiter, e.g

repeat for each item rItem1 delimited by "="
   <do stuff with ritem1>
   repeat for each item rItem2 delimited by ","
      <do stuff with ritem2>
   end repeat
end repeat
