I know Matthias warned us that AppleEvents.pm comes with no documentation. I«ve got the docs for Aebuild & al from the Alpha(text editor) distribution, but I«m stuck until I can lay my hands on some docs, or at least a header file, to get the parameters right. Specifically: # Usage: Mac::AppleEvents::AEBuildAppleEvent(theClass, theID, addressType, address, returnID, transactionID, paramsFmt, ... ). $ae = AEBuildAppleEvent('aevt',\ 'misc',\ 'dosc',\ 'XXXX',\ 'LAND',\ $retid,\ $transid,\ '----: "msg("hei")"' ); This tries to build an apple-event to "Userland Frontier", but the XXXX is supposted to be some kind of "addressType" , and 'LAND' is the creator type. I dont«t know if it will accept a creator-type, but I could probably find out if I had the relevant headers. For instance, what is "typeApplSignature" defined to be ? ( got that from the AE Builder/Printer docs). ----------------------*-*-*----------------------------- Rosetta for the mime impaired: Ç is <<, È is >>, equal sign is =, plain equal sign at end of line is line continuation, Œ is å ----------------------*-*-*----------------------------- HŒkon Alstadheim Prof. Dahlsgt. 48 N-0260 Oslo Tlf: 22 44 87 99
