Dear Henry, Great. The new addon already does it for me, also in Linux now. The f. thing only becomes apparent when I use Ddot by typing it, which I usually don't.
When activated from another verb or adverb it is fine: dfdx =: 1 : 'u Ddot 1 y' esqr dfdx 7 14 Likewise: dfdx =: 1 : 'u pderiv_jcalculus_ 1 y' esqr dfdx 7 14 and: (+/ ,-/ ,*/) Ddot 1 (7 5) 1 1 5 1 _1 7 Perfect. Thank you! Ben On Fri, 6 Sep 2019 at 19:16, Henry Rich <[email protected]> wrote: > No, no, your work revealed two problems, one of which I fixed in the > Addon.
