This probably reflects my complete ignorance, but...
All, I use RunRev in my lab: indeed, it does everything in my lab: all of my lab computers have it, except they have it as Metacard, but that shouldn't be an issue (or if it is, then I really have an issue, as it has to be in the Metacard IDE!). I never create standalones (well, I have done so to respond to beta-release questions, but that is not my usual use). I use Metacard to do everything: it is the hypercard of now. So, EVERYTHING I do runs in the IDE. I don't want it otherwise (I have self-modifying code and all sorts of horrors you don't want to know about), because I like the original hypercard ideal: it is how I work and think. Ok, that out of the way: I have a simple stack to edit face photographs to eye-align them. That means: simple scaling, rotating, and translating. Trivial. And not a problem. But, I need to locate the eyes in each photo first. So, I designed a simple stack to have the user *in the Metacard IDE* drag a line between the eyes to get the coordinates of the eyes in the photograph. Again, simple. BUT: in the Metacard IDE, as soon as I script-select the line to allow the user to draw the line so my code can get the rect, it switches the IDE to edit mode, which means any subsequent clicks on buttons (to indicate that the line has been drawn, etc.) put that button (or whatever object) into edit mode, so the intent of the object is lost. Suggestions? Remember, they have to work within the Metacard IDE, and I can't know ahead of time when the user has finished drawing or adjusting the line. Obviously, the Metacard IDE itself has solved the problem (e.g., all of the IDE stacks remain in use not edit modes), but I remain baffled. -- Please avoid sending me Word or PowerPoint attachments.

crop command

For example, if you create an image object and use the paint tools to create an image, it can be cropped with the crop command, but if the image object is sourced to a file, the crop command returns an error.

One last change; HP worked hard to find the colours for the keys that would work for all, especially those otherwise known as colourblind; hence the, for some, odd beige/yellow keys, and the faded cyan keys. But, in tests, these colours really do work for all including monochromats.

Re: [OT-Rodeo] Last minute call to get onboard with pre-realase conditions!
Ignoring the repeated spelling error, I chose not to buy-in to the early release bargain (and, it is a bargain); Instead, I want Jerry et al. to be able to leverage this thing to the point where it is actually affordable *for them*. So, I will wait and pay the full freight. I am so impressed with what they have accomplished to this point that full freight on just that, alone, is worth it.

Re: Naming Custom Properties
If you note in the Dictionary there is a comment from me on this ``hiccup'' of the custom properties, and it represents a long-standing complaint of mine (i.e., that all custom property names should be quoted literals or the contents of some variable). The problem is this: if variable fred has not been defined, then set the fred of this stack to myArray will, of course create the custom property fred with the contents of myArray. However, if fred has the contents mary then the same line set the fred of this stack to myArray will create the custom property mary with the contents of myArray. And this latter syntax is very convenient for creating custom properties with custom names on the fly. However, to be consistent, the name of the custom property should be a quoted literal when not the contents of a variable name, such that the lines: set the fred of this stack to myArray put fred into mary; set the mary of this stack to myArray do the same thing. The line set the fred of this stack to myArray should throw an error if fred is empty. Unfortunately, nobody at RunRev seems to agree with my desire for a consistent syntax.

I waisted a big chunk (no xTalk pun intended) of time rediscovering that, and I'd just like to confirm that that is the case. I'm also wondering whether anyone can point me to where this convention is discussed in the Users Guide or built-in dictionary.

Re: use-revolution Digest, Vol 79, Issue 28
What do I do? Rail against the fact that, sensibly, the engine translates all file references to one form, but fails to do so for many other utterly trivial differences. So, one is always forced to check for the OS (see the dictionary for all the ridiculous exceptions). Why? Why doesn't the engine, as with file paths, choose one style? It drives me nuts that in the IDE associated file references, for example, are different from that in the standalone, depending on the OS. That is just maddening, and also one reason I rarely produce standalones: in the IDE *almost* all remains constant over OSs. But create standalones and one spends way to much time compensating for silly differences over OSs that should not matter. To make the point clear that is is not just RunRev that maintains this nonsense. Take a look at this quintessential cross-platform app, R. You want to access text data in a rows by columns format on the clipboard by command in Mac OS X, you use: data.dat - read.table(pipe(pbpaste), header = TRUE), but on Windose, you use: data.dat - read.table(file(clipboard), header = TRUE). Why? Why wouldn't something so primitive be coded in the engine? Indeed, we all write a function in to handle the translation over systems, but, seriously, why should we have to? Same in RunRev. It it is a RunRev function or command, it should be identical over all systems. Period. If I see: ``how to do X on system y'' in RunRev, it should be followed by a single command for all systems. I admit, it is often no more than a switch command and a 3-line wrapper, but, really, why should it be even that? RunRev has probably spent more time writing the damn dictionary explanation of the exception than it would take to just make the the switch and 3-lines of code inherent in the code.

RunRev and Linux
I have been an Apple user since the Apple ][, and have purchased upwards of at least 100 machines from Apple in that time; but, lately, I have been playing with Ubuntu Linux. And, I must admit I am impressed. Most of my work on Macs is done with open-source software (mostly LaTeX and R), but I really rely otherwise on Matlab and RunRev. Really: about 90% of the work *in my lab* uses those two tools. Octave (open-source) and R can, combined, do most or what I use Matlab for, but there is no open-source replacement for RunRev. I really need it to work. I don't compile apps, I run everything in the (MetaCard) IDE. So, if I could be assured that the RunRev (especially the Metacard) IDE worked adequately in Ubuntu Linux, I would shift to purchasing cheap Intel machines for all my work and use Ubuntu Linux. My lab runs on tax-payer dollars, so any savings I can make benefit us all. Advice, comments?

Re: Rev IDE vs MetaCard IDE

But, I am not a fanatic about it: I encourage all my students to begin with RunRev using the RunRev IDE, and I use it on those occasions where I need to develop a complicated (read prettified) interface. However, those who go on to become the more proficient programmers seem to drift to the MetaCard IDE as they gain experience. The main difference is that the MC IDE, for the most part, because it is so close to the engine, stays out of your way.
