Is it Windows 7 32-bit or 64-bit? 64-bit OS's can't run 16-bit programs (most DOS programs are) and 64-bit Win7 doesn't have command.com. If it's 32-bit, try Win+R and type command.com, or perhaps use the "Search programs and files" feature.

MD5... that seems to be a bit too much It's another hash function, and has some desirable features including the difficulty of making something with a certain hash. Only problem is computing it will take a bit longer than you would probably like (probably on the scale of a couple programs a second) because it involves 32-bit calculations, which are more difficult in Axe. However, MD5 is not very secure (a few seconds on a modern PC to break it), and moving to SHA-2 is, best put, ridiculous. It mainly depends on the protection you want. If you want more than a simple checksum or variations thereof, I can only think of MD5... Somebody else can probably tell you more than I have Link to documentation on MD5

Could you post your results in case someone else has the same problem?
The .rom file is just a raw binary file containing the contents of the Flash ROM. The first 16KB of the file is page $00, the next 16KB page $01, and so on until either $1F, $3F, or $7F for 83+, 84+, and 83/84+SE respectively. In the same order, the resulting sizes are 512KB, 1MB, and 2MB.

We have archiving and unarchive via the "Archive " and "UnArchive " commands, which take a pointer to a name and return 0 if the operation failed, and IIRC 1 on success

Typically transmission errors (TI's transfer protocol uses it). It can as soon as the degree sign (for address-of) becomes official. (You have to be able to select an arbitrary page, which can be done by manually setting a "file pointer")

It depends on what you're checksumming In short, you'd calculate it for the normal version, and check with something else. Also, there are more advanced algorithms which make faking more difficult. (The checksum example I gave is more for error-checking than anything else, and is easily bypassed) However, I'm not sure how practical some of them are.

Checksum? There are several forms. The simplest is the sum of all bytes mod 16. Example code that displays the checksum of prgmTEST in RAM:
GetCalc("prgmTEST")->P 0->A {P-2}r+P-1->E For(X,P,E A+{X}->A End Disp A>Dec

There's also a "ld (addr),hl" You should be able to use that to solve your problem Edit: I might look at the code myself later.

Qazz, a lot Especially if you include Archive Do you mean apps, programs, or something else, though?

A picture. And no, pixels are squares

Most definitely. A feature seems required It's just that awesome

Note that dragging and dropping doesn't work, actually, at least for now. (My mistake, noted earlier)

Finally, Buckeye gets around to adding it (We're very appreciative) Good luck with whatever this is for (contest, I suppose?) Edit: 1000 th post!

Oh, I thought this was in relation to making an OS Undefined for regs, $0000 for PC, $0000 for SP (I think), IM 0, most other things should be zero'd, too, but I'm not sure

Okay. Good luck with whatever you're trying to do
