The A2 Repository.

21 May '23

Hello again, Consequent to the shift from SVN to Git, I've revised the introductory paragraph about the A2 Repository. https://en.wikibooks.org/wiki/Oberon/A2#The_A2_Repository Suggestions for improvements welcome. My knowledge of Git is minimal and haven't tackled the usage instructions yet. https://en.wikibooks.org/wiki/Oberon/A2#In_a_Unix-like_System https://en.wikibooks.org/wiki/Oberon/A2#In_Windows Will read https://en.wikibooks.org/wiki/Git before revising those sections. Suggestions welcome. Thx, ... P.L. - mobile: +1 778 951 5147 VoIP: +1 604 670 0140 sip:461697@sip.diamondcard.us

Finding the command which produced an Oberon subsystem in UnixAos.
by peter＠easthope.ca 21 May '23

21 May '23

For releases of UnixAos since some years ago this line in Configuration.XML starts an Oberon subsystem. <Setting name="Oberon subsystem" value=" Oberon.Start Oberon 1200x860 0 19 ~"/> In UnixAos release 4929, on an old Sharp Mebius PC-CB1-M1 the Log reports this. Autostart: executing Oberon.Start Oberon 1024x700 0 20 ~ Autostart: error executing Oberon.Start Oberon 1024x700 0 20 ~: Command Oberon.Start not found In 4929 an Oberon subsystem can be started from the menu. The Inspector should help to find the command which the menu invokes. Any guidance for that? Thanks, ... P.L. - mobile: +1 778 951 5147 VoIP: +1 604 670 0140 sip:461697@sip.diamondcard.us
