Yes, it runs on OS/2 1.3 and OS/2 2.11. Not on OS/2 Warp 3.

Turns out I misread the popuplog.  it's not a stack problem.  I cranked up the debugger to see what the code was really doing that triggered the trap.  The trap is at

035B                 les     di, pntr_2FC8   ; MartinI trap here

so it's a pointer problem.  The pointer is set at:

0293                 call    far ptr WinLoadPointer
0298                 mov     word ptr pntr_2FC8, ax; return pntr not handle ??
029B                 mov     word ptr pntr_2FC8+2, dx

What is odd about this is that based on the code, WinLoadPointer is returning a pointer, not a handle like current versions of WinLoadPointer.  I have to assume that this app was built to run against a really old version of PM.  Possibly for OS/2 2.1

The pointer returned by WinLoadPointer looks OK, but the selector (1b30) is a ring0 selector which is not usable by a ring3 app.

It would be interesting to see if someone with an OS/2 2.x install can run this app.

Interesting, I wasn't sure how to run it, as well as not having the local tide database for here. There's a whole rabbit hole on the tidal databases. Seems they were public domain but no more and my government is worried about commercial use :(
I am curious about the local tides, I'm perhaps 30 miles upstream from the ocean and the railroad bridge in town is considered the end of tidal waters.
I'll have to read up on the time zone support and whether x:\sys\apps\timeset\tz_en.lst that is installed by AOS is good enough. Seems it should be taken care off by the operating system and ideally installed in %ETC%
Then there is the rabbit hole of when the time zones change. Here the Province passed a law to switch to DST when ever you guys get around to it.

I unzipped the program files into a directory. I downloaded and extracted the harmonics file

https://flaterco.com/files/xtide/harmonics-dwf-20251228-free.tar.xz

I set and environment variable to the location of my harmonics file

Code: [Select]
set hfile_path=\suntanv6\apps\xtide\dist\harmonics-dwf-20251228-free.tcd
I ran the program, but I now get a message about time zone support.

Code: [Select]
tide -l "Santa Cruz"

Indexing \suntanv6\apps\xtide\dist\harmonics-dwf-20251228-free.tcd...
XTide Fatal Error:  BROKEN_ZONEINFO
Your platform appears to have broken time zone support.  You need to have a
reasonably modern version of the time zone database that is available from
http://www.iana.org/time-zones.

Hello Dave

I created this repo: https://github.com/OS2World/APP-SCIENCE-XTide
Let me know if you think that way is fine (the program and the library), otherwise, just delete the files and set it as you like it.

Also, a quick tutorial on how it works would be appreciated just to test it out.

Regards

Hi Neil, can you test tide.exe. Need https://flaterco.com/files/xtide/harmonics-dwf-20251228-free.tar.xz along with SET HFILE_PATH=location/of/harmonics-dwf-20251228-free.tcd adjusted to your install. Not sure of the expected dir separator in the SET statement. I'll include the man page.
Still working on the web server, stupid IPv6 stuff and how to handle daemon. Might try the xtide too.
Edit: The missing DLL

Will it work with python 3.9 ?
How to safe install python 3 without disturbing python 2 under arcaos v5.1.1 with valid Arca noae support ?

Sure. First try python --version to see what you have installed, here,
Code: [Select]
H:\tmp>python --version
Python 3.13.2
if you need to install Python3, IIRC, "yum install python2.7 python3" then "yum update"

Martin, can you split Neil's xtide comment into a separate thread?
Also perhaps create git archives of https://flaterco.com/files/xtide/libtcd-2.2.7-r3.tar.xz and https://flaterco.com/files/xtide/xtide-2.15.6.tar.xz

Thanks Steven

What should be the command to modify the stack of a 16bit app to make it run?

How much should I put on the /STACKOS2 ??
-- exehdr /STACKOS2:0x00000 poker.exe

The XTide program shows the tide table for a particular location. It worked for years, but stopped a couple of weeks ago when the harmonics fiie expired.

http://hobbesarchive.com/?dir=%2F&stype=all&sort=type_name&search=xtide&submit=Search


It's still under development here:
https://flaterco.com/xtide/files.html

But there is no longer any OS/2 version.

Although it is an X program, there is also a command line version, tide.exe, which was more useful for OS/2.

Is there any hope for building the current release; at least the command line version?
