Can someone please help me with this? I compiling a program with the Digital mars compiler and ran into the following error message:

e:\programming\source_code\C++\Lab>sc lab6
Fatal error: unable to open input file 'iostream'
--- errorlevel 1

I'm positive the file is there but am unsure of how to configure the compiler to see it!

1) 'iostream' should be 'iostream.h' (if you mean standard header file
located in dm/include)
2) You may check file sc.ini in DM\Bin
     there should be INCLUDE="%@P%\..\include"...
3) If all this does not help, type 'set' in cmdline and look for INCLUDE
environment variables. Once had trouble when Builder's include prevented DM
from working.

Yes. it is my understanding that the C++ Standard is to use <iostream> when including preprocessor directives vice <iostream.h>, unless referring to programmer defined header files, in which case a "xxxxxx.h" format is used. I this not the case in DMDC++?  I have, nevertheless, attempted both approaches and have failed miserably in both cases.

the current INCLUDE statement in sc.ini reads as follows:

INCLUDE="%@P%\..\include";"%@P%\..\mfc\include";"%@P%\stl";%INCLUDE%

my current path reads as follows:

E:\dmd\bin;E:\dmd\include;E:\dm\bin;E:\dm\include;

None of these settings rectify the aforementioned problem.

path?
set INCLUDE=e:\dm\include;

No that doesn't work either.

Where is the file iosteam.h?

Try to use the compiler as
sc -Ie:\dm\include <file>.cpp

That does it Jan. Thanks.

Just a couple more questions! I noticed that my program wouldn't compile when I used

using namespace std;

is it safe to assume that it is not supported in DMC++?
Is this also the reason for having to provide the extension on all includes
(e.g. #include <iomanip.h> vice #include <iomanip>)?

Still means one of the other things have not quite been setup correctly.

That's correct.

Correct.
