Hi Luìs, The problem here is the verb rank of the fork, see https://code.jsoftware.com/wiki/Vocabulary/slash#dyadic, section More information, point 2.
The verb rank of a fork is infinity: (+-*) b. 0 _ _ _ so this does not work as expected, 1 2 (+*-)/ 3 4 _8 _12 but restricting the fork to work at rank 0 does: 1 2 (+*-)"0/ 3 4 _8 _15 _5 _12 Best regards, Jan-Pieter On Thu, Dec 2, 2021, 21:12 Luís Alberto Lucas <[email protected]> wrote: > Shouldn't a train of verbs expand nicely into tables like a primitive verb > does? > > For example: > > > 1 2 (+*-) 3 4 > > _8 _12 > > > is ok but > > 1 2 (+*-)/ 3 4 > > > shouldn't it be > > _8 _15 > > _5 _12 > > > instead of > > _8 _12 again? > > > JVERSION > > Engine: j903/j64avx/windows > > Beta-v: commercial/2021-11-16T21:51:09 > > Library: 9.03.08 > > Qt IDE: 1.9.4/5.15.2(5.15.2) > > Platform: Win 64 > > Installer: J903 install > > InstallPath: e:/program files/j903 > > Contact: www.jsoftware.com > ---------------------------------------------------------------------- > For information about J forums see http://www.jsoftware.com/forums.htm > ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
