Failed{alpineDownOrCommunications, alpineDown, authenticateFailed, badCallee, grapevineDownOrCommunications, mismatch}.Establishes a new runtime binding to the Alpine instance specified by fileStore, and establishes an RPC Conversation with the server on which that instance is located. caller = NIL means caller is the logged-in user and derives the key from the password.Note:  if a call using a Handle fails via RPC.CallFailed[unbound], this generally means that the server has crashed and restarted since the handle was created; discard the handle (and any handles derived from it) and create a new handle.Client errors are:authenticateFailed:  bad caller name or key.badCallee:  bad server name.mismatch:  for example, version incompatibility.The other errors indicate a problem with ethernet access, grapevine, or alpine:alpineDownOrCommunications:  can't contact alpine;  may be communications or server down.alpineDown:  alpine server is down.grapevineDownOrCommunications:  can't contact grapevine;  may be communications or server down.Edit LogInitial: Kolling:  February 14, 1983 2:45 pm:  package to aid clients, in conjunction with AlpTransaction and AlpFile.‌ت*  –"cedar" styleک Jڑœ™ڑœ™Jڑœ!™!J™—unitڑدk	ک	Icodeڑœ‌œ_کwLڑœ‌œک-Lڑœ‌œک.Lڑœ‌œک4Lڑœ‌œک/Lڑœ‌œک—ڑœ‌œک Lڑ‌کLک Lڑœ‌œک.Lڑœ‌œک.Lڑœ‌œ‌œک(Lک Lڑœ‌œ‌œ1کMLڑœ‌œ‌œ&ک@Lڑœ‌œ‌œ+کJLڑœ‌œ‌œک"Lڑœ	‌œ‌œ'ک>Lڑœ‌œ‌œک!Kڑœ‌œ‌œکڑœ‌œ‌œکLک3Lک+Lک-Lک/Lڑ	œ‌œ‌œ‌œ‌œک!Lک-LڑœکLک—ڑ
