Has anyone tried this? Type: {'''' (Important: NO CLOSING BRACE!) You will get back an apparently empty list... But NOW try: 1 GET Big deal, right? An empty stack... ok... well then, try DEPTH Hmmm... There's something there? Try 123 SWAP Weird, huh??? You can DUP it and play with it all you want... It is a type 8 object (program)... I just found it so I haven't screwed around with the scanner to figure out what exactly it is... Is it a NULL program? I can't really think of any use for it (not yet anyway)... People keep asking about the possibility of speeding up the 48sx... The "Gurus" of this discussion brush it off as impossible immediately... They say, "nope... can't be done... processor is already at full speed" Well, although this is true, might not there be other avenues to explore? In particular, is it possible to disable the alarm and/or clock system??? Are these hardwired into ROM, or is there a way to avoid this time-consuming task? (Or is it not time consuming at all? Perhaps there is a dedicated alarm interrupt generator? Whatever the case, I'm sure it is apparent to anyone that the HP-28S kicks the pants off of the 48sx when the 28S is in FAST mode... Therefore, I can only assume that there is more overhead being performed on the 48sx... My 28s and 48sx just about tie (in NORMAL speed on the 28s) when I run this (rather ridulously simple) 'benchmark': \<< 1 1000 FOR A NEXT \>> So, my point is: Has anyone explored every possible avenue of speeding the 48sx up? It is sad that such a wonderful machine should have such annoying delays... By the way, is there anyone else out there who feels that the Equation Writer is a useless waste of address space??? It so incredibly slow. I can't imagine anyone actually keying an equation in during an exam and waiting for it to digest the information. (However, I must admit that I do use it to enter integrals and summations as I keep forgetting the RPN format... :<) XLIB is a reserved word... Is there a way one can enter an XLIB name if one knows its number??? ie., XLIB 1792 2088 or whatever? One more thing, if you wish to exclude the \<< and \>> from your programs and your programs are contained inside a large loop (ie., \<< DO ... END \>>), then an easy way to perform this task is to use { DO ... END } and then use 1 GET... This will return the raw DO loop to the stack (without any delimeters)... To edit it again, simply put it in a list using 1 \->LIST. I have more to say, but it's very late here and I'm very tired... Good night all... ---Xeno (Gary Snethen) tnan0@isuvax tnan0@ccvax.iastate.edu P.S. My high scores on Syzygy are: 244 with border and 579 without...
