I've read that this is doable, but I can't find a single example. Can someone show me how? I just want to execute a simple script like

tell application N
name of windows
end tell

where N is the psn of the app. If it's possible I'm assuming I just need to annotate it correctly. The background is that this script will be called from a cocoa app, if that helps.

You have a choice of means when working at this level. To translate from a PSN to a name look in Processes.h for ProcessInformationCopyDictionary() to get a name for a PSN. Otherwise using a PSN is the traditional way to set the target of an AppleEvent. Use typeProcessSerialNumber and the PSN you've obtained to set the target for AppleEvents. Using an AppleEvent directly instead of an AppleScript call will give you faster performance.

NSAppleEventDescriptor *psnDesc = [NSAppleEventDescriptor descriptorWithDescriptorType:typeProcessSerialNumber bytes:&psn length:sizeof( psn )];

+ (NSAppleEventDescriptor *)appleEventWithEventClass:(AEEventClass)eventClass eventID:(AEEventID)eventID targetDescriptor:psnDesc returnID:(AEReturnID)returnID transactionID:(AETransactionID)transactionID;
