I'm new with Nokia C++ SDK. I run into problem with abld command. Could someone give a hand?

I try to build the HelloWorld example. When I type the following command:

C:\Symbian\6.1\Series60\Epoc32Ex\HelloWorld>bldmake bldfile

BLDMAKE - Project building Utility (Build 227)

BLDMAKE {options} [<command>] [<platform>]

<command>: (case insensitive)
BLDFILES - create build batch files
CLEAN - remove all files bldmake creates
INF - display basic BLD.INF syntax
PLAT - display platform macros

<platform>: (case insensitive)
if not specified, defaults to "ALL"

Options: (case insensitive)
-v -> verbose mode
-k -> keep going even if files are missing

and then command
C:\Symbian\6.1\Series60\Epoc32Ex\HelloWorld>abld makefile wins

I get this error notice:

Bad command or filename

Problem is the same with every project platforms (wins,resource,vc6)

My PC's Operating Systems is Win98 and I have Microsoft Visual 6.0 C++. Do this may have something to do with my problems?(I know that the SDK requirements are for WIN NT, but the SDK's Java version works fine with Win98)
