Re: delete the last RETURN in a list

[Irv Kalb]

It sounds like you do have some confusion between a list and a 
textual representation of that list.  If you need to build up these 
items into a list (maybe for saving and using elsewhere), you can do 
it like this (untested e-mail Lingo):

fileList = []
repeat with i = 1 to the maxInteger
  thisFileName = getNthFileNameInfolder(<your target folder>, i)
  if thisFileName = EMPTY then
    exit repeat
    add(fileList, thisFileName)
  end if
end repeat
Then to display the list in a text or field member

listAsString = ''
nItems = count(fileList)
repeat with i = 1 to nItems
  thisFileName = fileList[i]
  put (thisFileName & return) after listAsString
end repeat
delete the last char of listAsString  -- eliminate final extra RETURN
member("<your display member>").text = listAsString
Then you still have the list in the variable fileList.

However, if you just want to display the list of files, you can 
eliminate the list entirely like this (again untested e-mail Lingo):

listAsString = ""
repeat with i = 1 to the maxInteger
  thisFileName = getNthFileNameInFolder(<your target folder>, i)
  put (thisFileName & return) after listAsString
end repeat
delete the last char of listAsString
member("<your text member>").text = listAsString

Hi List,

I getNthFileNameinFolder into a gSoundList an put RETURN after every 
filename then
on mouseUp
  nLine = the mouseLine
  if nLine > 0 then
    sprite(me.spriteNum).member.line[nLine].hilite()gSoundList[nLine]
  end if
end

When I click below the last filename in the scrollable field I get 
the error "Index out of range!" I can understand that.
How can I delete the RETURN after the last filename in the gSoundList?

TIA
Tony
