1. Dir() problem....
Hy,
(Happy new year.)
I have a problem with dir() (from file.e) .
If I want the index of files for example :
dir("*.exe")
It returns a sequence when there are files.
It returns -1 when there is no file with .exe .
So if I check for -1 at the return it works when
I have no files with .exe.
But if there is a file with .exe .
It gives an error message for the line I
check for -1.
Can someone help me ??
Bye,

If you are using something like:
object x
x = dir("*.exe")
if x = -1 then
-- do something
end if
-- do something
You need to change it to one of the following:
if compare(x,-1) = 0 then
or
if integer(x) then

object d -- gotta be an object, which can hold either sequence or atom (-1)
d = dir("C:\\MTDIR")
if atom(d) then puts(1,"Directory is empty")
else do_something_else()
end if

---- example:
object Directory -- an object can hold an atom OR a sequence
Directory =3D dir("*.exe")
if atom(Directory) then
-- no sequence, so no exe files found
puts("Nothing found")
else
-- there is a sequence
-- rest of your routine
end if
