Batch File Functions
InstallShield 2020 » InstallScript Language Reference
When you work with batch and configuration files, you can treat the files as normal text files, or you can use InstallScript functions designed specifically to modify batch and configuration files.
Ez and Advanced Batch Functions
There are two classes of InstallScript batch file functions—Ez and advanced. Ez functions are quick and easy to use because they have many preprogrammed features. If you need greater flexibility and control over the changes you need to make to configuration and batch files, use the advanced functions.
Return Value
InstallShield does not display a message if a batch function fails, but returns a value that is less than zero (< 0). The return value indicates whether the function performed successfully. You can check the return value and display a message based on the result.
