Thank you
But probably I miss something,
may be the #include "jfex.h", #include "jlib.h" are too few or different
version I have downloaded from github and installed I have the /8.07for
debian
here my results :
J jt = JInit();
int ret;
ret = JDo(jt,"0!:2 <'/etc/j/8.07/profile.ijs'"); -> ret 3 domain error
ret = JDo(jt,"0!:3 <'/etc/j/8.07/profile.ijs'"); -> ret 0 result of 0 if
an assertion failed, 1 if they all succeeded.
I tried on the ijconsole and with surprise I see an assertion, but
probably just because ijconsole already load the profile.
0!:2 < '/etc/j/8.07/profile.ijs'
NB. J profile
