-- HS says 50k limit on data file??? (http://discussion.visorcentral.com/vcforum/showthread.php?threadid=2404)

I'm on the phone with HS tech support, and this guy is telling me that there is a problem downloading data files larger than
50K?!?! (Things like DOCs, etc.)

Can you download and read a large DOC? (w/ USB)

Help...

I have had no problem at all with downloading larger files.

I assume from the "Penguins & Palms" bit that you're using Linux. Anyone on an iMac (& using USB?)

Personally, I think they're full of crap.

I've got two DOC files on my Visor even as we speak that are >80KB. Desktop OS are NT and Win2K (serial cradle for both). I've got some PeanutReader files that are several hundred KB is size!

I can't imagine that the Mac is your problem. However, it might be a USB issue (i.e. they owe you a new cradle). I'm curious to know what HS Tech thinks is so special about data files. They're saying that large program files are OK, but that data isn't?!?

In doing some experiments, I've found that a particular DOC file (Hemingway's "A Clean Well Lighted Place") will be fine when HotSynced as a .prc, but gets corrupted as a .pdb! It's only 4K.

I don't know what's going on and, clearly, neither do they.

Grrr.

I know that there is no such 50K limit. When I was doing the Visor Speed article, I use a 1026KB file for testing.

When I got that file from MemoWare, it came zipped. Did you get it elsewhere in non-zipped form? If so, did you download it with Netscape Navigator?

I ask because I recall reading the Navigator (although it may have been IE - - it's one of the two) corrupted files with .pdb file extensions on download. (Yes. It is possible that I've got that backwards as well.)

In your case, did you just rename the file prior to syncing to fix the problem?

yucca, you do have it backwards

NS corrupts PalmOS files if you download them unzipped.

This is why some people are getting fatal errors after downloading Handsum.

Another reason to use IE!

Don't get me started on NS vs. IE. They both crash on my NT system daily. If I bring up FrontPage 2000 and then exit it, NS is guaranteed to crash soon after that. NS also seems to need more and more memory until it eventually won't display any pages.

When I am in IE and it crashes, the HotSync icon and everything in the taskbar disappears and never comes back until a reboot. I am of the camp that the browser should not be part of the operating system because of this.

Sigh.

getting back to the original post in this thread. when i first read it, a bell (small one ) rang in my head. could the HS guy be mistaken with dynamic memory? I've been reading a PalmOS programming book and it talks about dynamic memory and keeping local variables within a 12-36KB size range.

There is a chart that describes the breakdown of the dynamic memory:
PalmOS 3.1 = 128KB total dynamic memory
of which: system globals takes up 2.5KB, TCP/IP stack takes up 32KB, system dynamic allocation is more than 15KB, application stack equals 8KB which leaves about 60KB (or less) of free space where local variables can be stored when declared 'static'.

I'm not a programming guru (somebody help?!?) but does that mean that a program can't have more than 60KB worth of local variables inorder to operate on the PalmOS 3.1?

Just a guess at what the HS guy may have been thinking and possibly misinterpreting your problem?

I have a copy of the CCNA's curriculum glossary in iSilo format at about 260kb. Works fine...

Ah-ha! I think the problem is with ZipIt 1.4 on the Mac. I just tried unzipping with Expander, and it seems fine. I'll have to try the others now.

Thanks for the help. (Oh, and HS called back when they said they would!)
