A very simple way to get this pattern is to right click on a dts package using enterprise manager and selecting schedule a job. This will build a dtsrun command string. The caviat is that this is a series of guids built that include your 'version' of the package. If you alter the dts package you will need to repeat and replace the new string into your scheduled job.
Example string built: DTSRun /~S 0x0E053E075B1EB77B1C60F63A828E2E15C008C528661BD417 /~N 0x3FB6EE04EE88B29D14D4EB10556050C556204D3482855A0F41D7BBF32885D393671A8356D87C99B6928FE3D626F74F7E02A0A92AFFE2AA08 /E
