Re: FTP_list max entries 80 or list sequence issue

Kevin,
It's not clear to me how your code works, exactly. But, the fact that you're using a BASED() variable makes me very nervous. The system does not assign memory to based variables, so you have to allocate it yourself or point it at some other variable that does have memory assigned to it. Personally, I would prefer just defining an array and passing it and skipping all the extraneous pointer logic. 

For example, something like this:

D myList          s            256a   dim(10000)
D myCount         s             10i 0

  if FTP_list( ftp
             : '*.pdf'
             : %elem(myArray)
             : %addr(myArray)
             : myCount ) <  0;
    ... handle error here ...
  endif;

  for x = 1 to myCount;
     // do something with myArray(x)
  endfor;
So this example gets a list of files matching '*.pdf' in the current FTP server directory and returns them in an array named myArray(). myCount will tell you how many files were loaded into the array.
Personally, I think it's a lot cleaner this way than that business with the 'ListBase' and the constant of 80 and stuff like that. I think it' much easier to understand when you aren't doing the extra pointer logic and I think it's much easier to understand %elem() is telling FTPAPI how big your array is.

    Hi Scott,

    This was based on an example with a description that 80 was the max. So
    our code is like this

    D cMaxEnt         c                   80

    D pMaxEnt         s             10i 0   inz(cMaxEnt)
    D pLSArry         s               *
    D pActEnt         s             10i 0   inz(0)

    D ListBase        s          25600a     based(pLSArry)
    D ListData        s            256a     dim(cMaxEnt)

      If        ftp_List(ftp
                       : pRmtFil
                       : pMaxEnt
                       : pLSArry
                       : pActEnt
                       ) < 0

    So instead we could increase ListBase to 256000, and set CMaxEnt to
    2560.

    We then sort the array to ensure we then process the files in the
    correct order.

    I presume the max we could handle would be 16million/256 to file an
    array with file names? Not that I expect or hope to ever reach that
    number.

    Many thanks for your help.

      Hi Kevin,
      I'm not aware of this limit.  Can you tell me where you are seeing a
      limit of 80 entries in FTP_list()?
      I thought you could tell it your array size on the call to
      FTP_list()
      and could specify any size array that you wanted?
