Using a Command to Run an Application
After you create an executable image of an application, you can use it in a command that users enter to run the application. A command is an executable file that includes the image file name and any parameters that you specify. A command can be one of the following, depending on your system:
Windows:
icon 
UNIX:
shell script 
VMS:
DCL foreign command 
Creating a command requires, on your part, the most planning of all the access methods. However, using a command is most desirable in a full production environment, especially if many users with different needs are accessing the application.
Using a command provides these advantages over the other methods of running an application:
• Users can start the application quickly and easily.
• Users only need to know a single command to run the application, without having to remember syntax and component names.
• You can specify commands to control precisely how users access the application.
• You can create different commands for different users based on their functions, information needs, security levels or other factors.
For example, various users can access the order entry application. You can create various commands to:
• Let some users call a Browse frame to view customer information
• Allow clerks to call frames to perform such functions as adding new orders and updating customer records
• Let managers call the application to access confidential financial information
Each of these commands calls the application with a different start frame. You can create as many different commands as you need.
