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 defi
Hi
I tryied to acces several sensors via j dll
I posted some months ago a bare bone example
I think if you find an example how to access gps in c you could use j dll
Actually I made an artificial horizon with accellerometers .
But does not work good
If interested I can look for it and post it.

Fill =: verb define
:
|. x $ |. (x$'0'), ": y
)
5 Fill "0 a
Transform item of a to string
Add max number of patter in this case '0', x function parameter holds the
max length
Revert the string ex
take the max length (x)
Revert again the string
Example
Call Fill with 5 max length
And "0 needed

(I presume)
I have used a trik to delete data > of 7 bit but is very badd and lead to

Hello I am trying to learn J
and trying to make a function to tokenise strings
I have tried the E. command but I cannot have it working to search 1 char
token
ex:
[a=. ;: 'cc dd f h gg zz'
┌──┬──┬─┬─┬──┬──┐
│cc│dd│f│h│gg│zz│
└──┴──┴─┴─┴──┴──┘
(<'h') E. a
0 0 0 0 0 0
but w
