+====== Mid to late October work ======
+I didn't get around to writing a blog post last week, so this one covers two weeks' worth of work.
+**2024-10-27**
+===== Instruction set reference =====
+[[https://hg.pushbx.org/ecm/insref/rev/0049d9068a70|Fixed insSTOSB stating that it "sets the flags accordingly"]]. Also add to other string instructions that flags are not modified (ins, lods, movs, outs).
+===== lDOS boot =====
+  * [[https://hg.pushbx.org/ecm/ldosboot/rev/0e3f8cc013a0|Add section on FSIBOOT]] to the documentation
+  * [[https://hg.pushbx.org/ecm/ldosboot/rev/d0f336f6ac05|Add sections on ROM-BIOS and MBR to sector]] to the docs
+  * [[https://hg.pushbx.org/ecm/ldosboot/rev/f4e0d0ad0612|Fix newly added hyperlinks]] in docs
+  * [[https://hg.pushbx.org/ecm/ldosboot/rev/45ff3831edd5|Mention patchqry]]
+  * In iniload lDOS entry [[https://hg.pushbx.org/ecm/ldosboot/rev/efdfdbf93f95|check for lsvLoadSeg underflow]]
+  * [[https://hg.pushbx.org/ecm/ldosboot/rev/0a8f90c39839|Update attribution year]] of iniload.asm
+  * [[https://hg.pushbx.org/ecm/ldosboot/rev/e8135bddf252|Update iniload.asm comments]] listing known lDOS signatures
+  * [[https://hg.pushbx.org/ecm/ldosboot/rev/c41773c20225|List lDXX (unset) signature]] in iniload.asm and documentation
+===== lDebug =====
+[[https://hg.pushbx.org/ecm/ldebug/rev/e19b672622be|Update dbitmap Extension for lDebug]] to add STR mode. This allows to display a string using the embedded font.
+The STR mode patch includes the \M escape code which causes the next byte to be mirrored.
+In a separate revision [[https://hg.pushbx.org/ecm/ldebug/rev/49c7d7ea4ce3|the \H escape code is added]] which takes an alphanumeric byte and displays a blank of the corresponding width, mainly for ''\H4'' to display a half-width space.
+(Backslashes to be displayed must be escaped as double backslashes.)
+Here's a fun script to try with the updated ELD, logo.sld:
+<code>@?version
+@ext printf.eld "\r\n"
+@ext dbitmap.eld run set1 '#' end set0 ' ' end str "\MLDebug"
+@ext printf.eld "\t   Presented by BTTR Software\r\n"</code>
+(The reverse capital L is an acceptable way of rendering the first letter of "lDebug" or "lDOS".)
+===== Enhanced DR-DOS =====
+Pick two changes from SvarDOS:
+  * [[https://hg.pushbx.org/ecm/edrdos/rev/820c1299fa5c|Re-test buffer dirty status after recursive buffer flush]], to address [[https://github.com/SvarDOS/edrdos/issues/120|an error during cross-drive copying]]
+  * [[https://hg.pushbx.org/ecm/edrdos/rev/243525ce79db|Prefer discarded buffer]] when searching a buffer for new data (performance optimisation)
+Further, [[https://hg.pushbx.org/ecm/edrdos/rev/92e280052d42|the lDOS version string got updated]] to 2024 October.
+===== fixmem =====
+  * nasm.mac: [[https://hg.pushbx.org/ecm/fixmem/rev/d8da6c3c02c4|cap-insensitively define labelsize labels and ret in proc]]
+  * [[https://hg.pushbx.org/ecm/fixmem/rev/918e281a5dc6|replace %out directives]] by %warning
+  * [[https://hg.pushbx.org/ecm/fixmem/rev/bb5746a5aca6|ignore .xcref, .cref, name directives, and handle .xlist]]
+  * [[https://hg.pushbx.org/ecm/fixmem/rev/2c662df245e9|add support for I_AM and I_NEED macros]] used by MS-DOS v4 kernel sources
+  * detect comment that [[https://hg.pushbx.org/ecm/fixmem/rev/54d6fb07091f|indicates NASM original macros to skip remainder of a file]]
+  * nasm.mac: [[https://hg.pushbx.org/ecm/fixmem/rev/bbc415e7c4c0|insert NASM original macros comment]]
+  * [[https://hg.pushbx.org/ecm/fixmem/rev/a3e819139fbd|allow SIZE operator to specify differently-capitalised name]] of a structure
+  * [[https://hg.pushbx.org/ecm/fixmem/rev/90f95446fb48|switch ENDS to define a _struc_size suffixed label]] rather than _size, as _size sometimes clashed
