	Of course. Prerelease.2 sources can changed wihtout any announce and is 
often modified. Bug you have seen was fixed in october.

	Warning : first RPL/2 language was created a long time ago to reuse 
some programs I have written for my old HP-28S (and not for 48 or 49 
that didn't exist). I have added some stuffs that were missing before HP 
sell HP48. Thus, there are some differences between RPL/2 and 48's RPL 
or 49's RPL (file management, SELECT/CASE/END, PostScript output, 
sockets support, multitasking, databases [today only mysql wrapper], 
VOLATILE and STATIC variables, locks, POSIX SIGCONT support and in a few 
weeks real time support and asynchrone procedures calls...)
