I haven't tried to recreate this yet, but: what is the problem? Should
it not get a domain error? Or is it the odd name 'fastincld4B7g0'?

Something for Henry, I think.
Starting to have a look at Louis' variants on Vadim's approach, I tried
using debug on "fastincl" , invoked by ctrl-K.
Setting stop on all lines in either fastincl =: cmp fastmax
or in fastmax and then running
fastincl lines
results in
"
domain error
fastincl[header] cmp fastincl
"
in debug's middle pane,
with
"
[0] cmp fastincld4B7g0
"
displayed in the top pane
The lowest pane displays:
"
cmp v +./@E.&>
fastincl v cmp fastincld4B7g0
"
This happens in both J 9.01 beta and J 8.07, under Windows 10 .
Debug seems ok however when explicitly running "(cmp fastmax) lines "
So it's probably something to do with fastmax being an adverb, but here
are
Louis' definitions to save hunting for them in the correspondence:
fastmax=: 1 : 0
B=. C=. 1"_1 y
while. +./C do.
i=. C i.1
B=. 0 i} B
B=. -.@:u&(i{y)&.(B&#) y
C=. C *. B
B=. 1 i} B
end.
B#y
)
cmp=: +./@E.&>
fastincl=: cmp fastmax
debug behaves just the same for
fastincl 'abc'
so I won't bother defining "lines" here.
This is probably known behaviour, but it's new to me!
Thanks,
Mike
