Batch files under Windows 9x

I am trying to write 2 batch files. The first must run in a window because is contains several “Start” commands.
As I exit this batch file I want to call a new batch file that must run in DOS mode without windows.
In either of the two batch filesI need to find and delete all files named ~*.*. Can someone shou me how to do this using only DOS commands? How do I redirect the command DIR /s /b ~*.* to the DEL command?
Any suggestions?
