This script can be added to DirectoryOpus 4 either as a button or a hotkey and allows you to retrieve a file version (internally, by using the stock C:Version command) and to display the version in a convenient pop-up window.

The script is designed to not use any external tools and has no other requirements than a stock installation of DirectoryOpus 4 and the Workbench stock version of C:Version. The ARexx script works under the assumption that version strings must contain at least a number. This means that if some developer just supplied letters as the version string then this script will fail.

However, the script is excessively documented and is easy to adapt to use a more comprehensive tool that is able to extract an unconventional version string.

• DOpus4-Version12.lha on AmiNET

1. Extract the archive
2. Place DOpus4-Version.rexx wherever you see fit (it is tidy, for example, to create an ARexx directory in DOPUS4: and then place your scripts there).
3. Open DirectoryOpus4 and right-click and go to Project→Configure
4. On the screen that pops-up, go to Buttons and create a new button somewhere where you see fit.
   1. Give the button a name (Version, for example) and create a new entry.
   2. Set the cycler to ARexx and click the magnifying glass to enter the path to the DOpus4-Version.rexx script.
5. You do not need to set any flags.
6. Save and exit and you are done.

In DirectoryOpus 4, select any file that is bound to have a version string and click the button you created. You can also select multiple files and the script will process them all one after the other while skipping files that do not have a version string.
