Re: FTP_list max entries 80 or list sequence issue
Scott,
Many thanks for that.
Will make some changes tomorrow and let you know how we get on.
Good to know that 80 was just not correct as the maximum entries.

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.
