            STRPCO     PCTA(*NO)                        
            MONMSG     MSGID(IWS4010)                    
            STRPCCMD   PCCMD('C:\RMS400\CDK') PAUSE(*NO)

this CDK is an EXE file. While running this I am getting a DOS prompt, to avoid this popup can i use RUNDLL32. If yes, how it can be used. what are the parameters i need to send in STRPCCMD.

This trick works for me under Vista Business to launch a DOS program without the annoying flashing DOS box.  Assumes CDK is an EXE.

Create a VBscript that starts the desired program in a hidden window (code below).
Use Wscript to launch the Vbscript

STRPCCMD PCCMD('wscript c:\runhidden.vbs') PAUSE(*NO)

Code for runhidden.vbs is below.
strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set objStartup = objWMIService.Get("Win32_ProcessStartup")
Set objConfig = objStartup.SpawnInstance_
objConfig.ShowWindow = HIDDEN_WINDOW
Set objProcess = GetObject("winmgmts:\\" & strComputer & "\root\cimv2:Win32_Process")
objProcess.Create "C:\RMS400\CDK.EXE", null, objConfig, intProcessID

Open in new window

The [ RunDLL32.EXE Shell32.DLL,ShellExec_RunDLL ] shell functions work very well. As always with STRPCCMD, the 123-char limit on the command string still must be watched. The alternative RUNRMTCMD can often be more useful than STRPCCMD, particularly when you don't know if the remote system is a Windows PC.

Gary PattersonVP Technology / Senior Consultant Commented:
Tom's right - RUNRMTCMD is a nice solution where you can use it.  It runs as a service on Windows.

When I run a command-window program (as opposed to a Windows program) on Vista Business using

STRPCCMD 'RunDLL32.exe SHELL32.DLL,ShellExec_RunDLL ipconfig.exe') PAUSE(*NO)

I still get the annoying flashing DOS box that pops and quickly disappears.  Using the WSCRIPT technique above, there is no visible artifact shown on the user's screen, plus with the 123 character limit, that long call really eats up your workspace.

Of course, you may see different behavior on other versions of Windows.  Just thought I'd mention my results.
