movq<p>OS/2, “DOS from drive A:”, and <code>EXIT_VDM.COM</code>:</p><p><a href="https://www.uninformativ.de/blog/postings/2025-01-03/0/POSTING-en.html" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">uninformativ.de/blog/postings/</span><span class="invisible">2025-01-03/0/POSTING-en.html</span></a></p><p>Maybe someone can confirm or disprove the hypothesis (HLT creates exception → OS/2 inspects next opcode). 🤔 It’s getting hard to find good sources on this.</p><p><a href="https://tilde.zone/tags/RetroComputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RetroComputing</span></a> <a href="https://tilde.zone/tags/OS2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OS2</span></a> <a href="https://tilde.zone/tags/IBMOS2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>IBMOS2</span></a></p>
movq<p>OS/2’s <a href="https://en.wikipedia.org/wiki/Shadow_(OS/2)" rel="nofollow noopener" target="_blank">shadows</a> are somewhat similar to symbolic links or Windows’ shortcuts, but different: The exist only as a feature in the GUI, not in the filesystem. The good thing is that you can’t break a shadow’s link by renaming the original/target. The bad thing is, well, they don’t exist in the filesystem. 😅 That feels particularly odd to me, given my heavily UNIX-focused perspective.</p><p>“Shadow” is kind of an unexpected name, too. In the German version, this is called “Referenz” (reference), which is quite a bit more intuitive, I think. 🤔</p><p><a href="https://tilde.zone/tags/RetroComputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RetroComputing</span></a> <a href="https://tilde.zone/tags/OS2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OS2</span></a> <a href="https://tilde.zone/tags/IBMOS2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>IBMOS2</span></a></p>
movq<p>Still trying to customize the keyboard layout on OS/2.</p><p>None of the resources I can find indicate that any file other than <code>KEYBOARD.DCP</code> is involved. And yet, my modifications only work in an OS/2 command window but not GUI applications.</p><p>I’m stuck. Might be time to ask for help … if I can find someone who still knows about this stuff. 🤔</p><p><a href="https://tilde.zone/tags/RetroComputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RetroComputing</span></a> <a href="https://tilde.zone/tags/OS2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OS2</span></a> <a href="https://tilde.zone/tags/IBMOS2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>IBMOS2</span></a></p>
movq<p>I guess finding out how to customize the keyboard layout on OS/2 is going to be one of my next projects. It’s quite annoying to be stuck with the standard layouts. On Linux, I made <a href="https://www.uninformativ.de/git/keyboard-layouts-3000/file/de_capsergo/xorg.html" rel="nofollow noopener" target="_blank">some adjustments</a> to the standard German layout and I’ve been using that since ~2010 now. There must be a way to do the same on OS/2 – just gotta find out how. 🤔 (Famous last words.)</p><p><a href="https://tilde.zone/tags/RetroComputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RetroComputing</span></a> <a href="https://tilde.zone/tags/OS2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OS2</span></a> <a href="https://tilde.zone/tags/IBMOS2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>IBMOS2</span></a></p>
movq<p>The JPEGs in my blog don’t render correctly in IBM WebExplorer 1.0. Should I debug this? 🤪</p><p>It’s kind of intriguing, ngl … Works in version 1.2 on Warp 4, though.</p><p><a href="https://tilde.zone/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>retrocomputing</span></a> <a href="https://tilde.zone/tags/os2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>os2</span></a> <a href="https://tilde.zone/tags/ibmos2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ibmos2</span></a></p>
movq<p>D’oh!</p><p>OS/2’s command prompt windows have a function which is called “Fensterinhalt verschieben” in the german version. The literal translation is “Move window content”. What could that possibly be? 🤔 Can you just drag-and-drop the window content to something else like a text editor? 🤔 The online help wasn’t helpful.</p><p>The english version calls it “Scroll” and as I read that, suddenly it dawned on me. When it’s active, you can scroll the window content using the cursor keys. 🥴</p><p>“Fensterinhalt verschieben” also makes sense now. The funny thing is, the german language has completely adopted the word “scrolling” (or “scrollen”) and it is deeply ingrained into our/my brain now. 😅 I simply didn’t get what “Move window content” could mean until I read “Scroll”. 🤦😬</p><p>Funny enough, Windows 3.11 has the same function but it’s called “Bildlauf”. The german translation of “scrollbar” is usually “Bildlaufleiste”, so that’s a little bit easier to understand …</p><p><a href="https://tilde.zone/tags/RetroComputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RetroComputing</span></a> <a href="https://tilde.zone/tags/OS2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OS2</span></a> <a href="https://tilde.zone/tags/IBMOS2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>IBMOS2</span></a> <a href="https://tilde.zone/tags/Windows311" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Windows311</span></a></p>
