exec.library always v40?

[rvo_nl]

Another thread from me, sorry. I just keep having issues and questions. Now that I finally have my harddrive and OS3.9 installation sorted, I wanted to modify this little script:
 
http://deliriumbbs.freehostia.com/Dualbooting_AmigaOS_4_and_AmigaOS_3.9.bbs
 
so that it allows me to select which OS to boot from (I now have 3)
 
however, no matter in what OS I try (okay, Ive only tried wb3.1 and os3.9) I always get version 40.x of exec.library, so the version check fails to work.
 
any idea why? something wrong with the syntax perhaps? can I check for something else that is made resident by the rom updates of either 3.9 or 4.0?
 
have a good night, all. and thanks for your answers.

Only OS 3.9 BB2 has a new version of exec.library and only if the new ROM update has been installed. All earlier versions, including BB1 and 3.5 work with exec.library V40.

something wrong with the syntax perhaps?

If you suspect a typo you should remove the >nil: and watch for error messages. Also try to enter the command in a shell window and see its result.

yeah thats what I did. I didnt get round to installing boing bag 1+2 this time, though it did cross my mind this could be the cause.
 
thanks, will continue next year
