When executing a Windows 95 batch file, Windows 95 launches a Windows program and continues immediately with the execution of the next instruction in the batch file. This might cause more than one program to run simultaneously.
The START command with the '/W' switch provides a effective means to force sequential execution of batch file commands. Insert
START /W
in front of the batch line that launches an application and Windows 95 will wait until that application terminates before execution the next batch file line or command.
This technique can also be used to prevent the simultaneous execution of multiple instances of the same DOS program.
