DIETER ENSSLEN: > make it simple It's not clear to me whether you're trying to use your handheld's file explorer or your desktop's file explorer. I think this process will be easier if you connect your handheld directly to your desktop PC, and use your desktop PC's file explorer to manipulate the handheld's file system.
If you can do that, then the installation instructions are straightforward. On http://www.jsoftware.com/stable.htm we read: 1. unzip in temp folder on desktop computer 2. copy j602 folder to Pocket PC \ folder (Confirm File Copy - Yes to All) 3. copy j602\J602 (shortcut .lnk file [1]) to \Windows\StartMenu\Programs 4. Start > Programs > J602. If you cannot connect your handheld directly to your desktop PC, then you must perform the same steps, only using the handheld's file explorer, and copying from the SD card as a source rather than copying from a temp folder on the desktop PC as a source. Unfortunately, we can't see your handheld's screen, so we cannot give you click-by-click instructions. But I did this a while back and it was dead easy. And from your messages, I infer you actually have a number of handhelds ([2]) and so (I assume) commensurate experience with their user interfaces and file navigation tools (which is why your phrase " and a few arrows and icons" confuses me -- presumably these are the file explorer's toolbar, which should not only be intuitive but very familiar, if you use your handheld a lot). That said, what I sense from you is a reluctance to get into, for lack of a better term, "computer stuff". So my concern is that, even if you get J going on all your devices, you're immediately going to hit the next hurdle, which is that J is a computer system. It's chock full of "computer stuff". Now, J is many things to many people. But one thing is it not is a CAS (as Devon pointed out), and if you go in with that expectation you're just setting yourself up for confusion and frustration. Yes, one of J's roles is an (note: an) executable math notation, but if you want to use it that way, you're going to have to change your expectation regarding the notation (J deviates from "standard" math notation intentionally and for good reasons). But "math" is not all J is, and if you use it you're going to inevitably going to encounter its "computer programming language" role -- this is canonical "computer stuff". For example, that's what seems to trip you up about spaces [3]. Written mathematical notation is lenient. Computer programs are not. Anyway, can I ask a silly question? Why do you immediately want J on all your these devices? I'm curious because, given that a handheld's IO is so limited and frustrating, I would not want to compound that with the frustration of learning a language I don't know yet, and making frequent errors. That is, I personally wouldn't see the value of having J on my handheld device before I learned the language (though I could definitely see the value of an application written in J on such a device, implying J would have to be there too) [4]. Do you just want to have J on your handhelds for its own sake? I can understand that, but if that's your reason, I might recommend deferring the problem of installing it until you've played with J in a larger arena for a while, and decided you like it enough to make the (apparent) frustration of installing it on a small device worthwhile. -Dan [1] Maybe you're having trouble identifying which is the .lnk file in your handheld's file explorer? [2] Actually, I'm curious, why do you have so many handheld devices? You just like the technology, or do you use them all? If so, do they serve different purposes? [3] But, as a general tip, put spaces anywhere you think you might need one, and preserve spaces in any code you get from someone else (e.g. via direct copy/paste). This won't hurt, and is analogous to "over parenthesizing" a mathematical expression when you're not certain of order-of-operations (e.g. when you were first learning PEMDAS). [4] Well, maybe I could/would use it in just immex mode, as a supercalculator; immex mode (noun phrase usage) is easy to pick up and become productive in. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
