In the Workspace area right-click on your project. Click "Options". In the Category area click on "Linker". On the first tab (Output) click on radio-button "Other" then choose "intel-standard" from the "Output format" combo. Click "OK".
After bulding the project you get one file with the project's name and the extension ".a90" in the folder "Release" -> "Exe". If you want, you can copy the file somewhere else and change its extension in ".hex" or you can directly use it from your programmer.
