Step Name - The name of the current step
Step Command - The command in which this step will execute. The command can use any variables that are part of the package as replacement values in the command. For instance, if "User::strVHDFilePath" had a value of "C:\ssis\myserver.vhd" when the command in the step above was executed the full command would be "del c:\ssis\myserver.vhd".
Timeout (Second) - The number of seconds you'd like this step / command to run before the process is killed. Setting the value to 0 means there isn't a timeout.
Success Exit Code - The exit code of the command which indicates the step was successful.0 is the default success code for the command line.
Window Style - The style in which a command window is shown. The four options are Hidden, Normal (show a normal window), Minimized (show a command window minimized) and Maximized (show a command window maximized)
Standard Output Variable - You can either have the output of command outputted to the command window (will go to the BIDS execution results or log if the window style is hidden) or store the output in a variable. This is useful if you are going to use the output from the command in a later task or command step.
