slowly I begin to understand,
first of all I have to define the load but I am not able to find the
information on how to use the foreign command 0!:x to load profile.ijs
once I will be able to load modules, to make a verb should not be a big
problem
I can embedded J command and macro functions in C++ classes

It appears that multiline definitions cannot be handled through a single
call to JDo:
". 't =: verb define' , LF , 'a =: 111 ' , LF , ')' , LF
|spelling error
Here's a keyboard session, annotated
".'t =: verb define' NB. enter this line
Here you get a prompt of 0 spaces, indicating that the JE is waiting for
keyboard input for the definition
a =: 111
)
After entering ), I get the 3-space prompt indicating the ". verb
completed execution.
t
3 : 'a=:111'
I don't know whether there is any way to create a multiline definition
using LF without going through 0!:x. If it's short yo could create
boxed strings:
". 't =: 3 : (''a =: 112'' ; ''b =: 113'')'
load is not defined until you have used 0!:x to load the base library,
as Bill pointed out.

The \r is the right one thank you
but even with the correct end of line I tried several combinations \r
and \n
but without success the error is value error or spelling error
also the profile.ijs when I try to load it with JDo give me back "value
error"
I have also put it in the executable directory but without success.

Perhaps those /r should be \r ?

Hello
I am trying to mix J with C++ in Linux
I have included in my C++ project jfex.h libj.h and libj.so
after calling JInit() I am able to execute simple sentences with JDo
and
get the result with JGetA
but I am not able to define more sofisticate behaviours ex. define J
function with verb define
ex.
int JDo(jt,"testverb =: verb define /r a=: 111 /r )");
fails with error: domain error
or loading module ex plot.ijs
fails with error: value error
do I am doing something wrong as missing some initialisation?
Cheers
Paolo
