Well, it's surprisingly difficult to move a value to the remember-when-off category... but i -can- provide a couple of patches... one which will -lock- it permanently ON. The other (which i'd choose) reverses the default from OFF to ON. So, if there's a session you -don't- want it, you use the normal setting procedure to kill it for -that- session only. (another request by folks is to have it remember the "Reverse L/R" and "U/D" items.. in older versions they -were- remembered) The lock-ON patch would be: R 53E42 1e 20 ; +2 R 53E43 00 05 ; +5 R 53E44 08 01 ; checksum -7 The usually-on patch would be: R 53E42 1e 1f ; +1 instruction R 57780 ff fe ; -1 checksum adjust The usually-on patch will -reverse- the meaning of the ON/OFF setting (so ON will be OFF and OFF will be ON), but that particular setting-section is too tightly coded for an easy flip of the display. So, choose one or the other of the above. Either one can be applied independently of the rest of my patch kit, or they can be added to the normal patchkit patch24a4.txt file and applied with the kit. Details: The first patch changes a branch-if-bit-set to a branch-always ;; (A-AE42) brset bra ae49 (i.e. skip next 3-byte instruction) The second one changes the branch-if-bit-set to branch-if-bit-clear. ;; A-AE42 brset brclr good luck --dick
