Would be great thx. I was already looking at a solution with the .sy macro to invoke an awk oneliner. But I d rather do it all in groff. Kind regards, Wim Stockman Op wo 23 jun. 2021 22:26 schreef Denis M. Wilson : > I have macros corresponding to Cs strchr and strrchr functions. > Do you want m

That is indeed what I used as a substitute. But it's not typographically very nice for setting out geometrical proofs (which is what I'm doing), where the three sides of the triangle should be of equal weight. On Wed, Jun 23, 2021 at 4:12 PM Oliver Corff wrote: > Hi Robert, > > is Delta \[*D] a
