Dan - for example:
'is' names_z_ 3
ic int01 isotimestamp script scriptd
scriptdoc scripts setbreak setfontsize setrl
shell sign sin sind sinh
skewness smoutput sort spawn spdev
split sqzint sqzrun ss ssdev
startupconsole stddev steps stringreplace symget
symset
However, my definition of "nl" differs from yours:
nl
4!:1
nl_z_
4!:1
Substituting the one you gave fixes the problem!
Where did you get this definition? I installed the latest J on my other
machine
and it has the same defective behavior.

I should've asked for the definition of nl , too. For comparison, here
is the definition of names from my J session:
names
[EMAIL PROTECTED]
nl
3 : 0
'' nl y
:
if. 0 e. #y do. y=. 0 1 2 3 end.
if. 1 4 8 e.~ 3!:0 y do.
nms=. (4!:1 y) -. ;: 'x y x. y.'
else.
nms=. cutopen_z_ y
end.
if. 0 e. #nms do. return. end.
if. #t=. x -. ' ' do.
'n s'=. '~*' e. t
t=. t -. '~*'
b=. t&E. &> nms
if. s do. b=. +./"1 b
else. b=. {."1 b end.
nms=. nms #~ n ~: b
end.
)
This last code block (in if. #t ... ) fulfills the semantics I
described. Note the E. in particular, which indicates 'is'&names will
look for names containing the substring 'is' , not the individual
characters 'i' or 's' .
I'm running J601c, but I just checked J601a, and the definition is the
same. So something else is wrong. Can you provide a simple demonstration
of the problem? For example, do this in a J session and post the results:
foo00_xxx_ =: 0:
Xfoo00_xxx_ =: 1:
fXX00_xxx_ =: 2:
Xoo00_xxx_ =: 3:
'foo' names_xxx_ 3
foo00
'*foo' names_xxx_ 3
Xfoo00 foo00
These are the correct results for the semantics I
described. If names were returning all names containing any of the
characters in x , then 'foo' names_xxx_ 3 would've returned all the
names defined on the preceding lines.
