[Jprogramming] Getting J to work with .NET

Mon Jul 12 07:25:23 HKT 2010

It's working for me with some statements in the ijs file but not when I
define a verb for some reason:
ijs file
result =: 2 + 2
square =: *:
centigrade =: verb define
t1 =. y - 32
t2 =. t1 * 5
t3 =. t2 % 9
)
Then I've got this code:
 var cSharpSession = new CSharpSession();
 cSharpSession.Load("C:/Playbox/JForTheWin/WillJWork/bin/Debug/script.ijs");
 cSharpSession.Eval("mark =: centigrade 5");
 var csharpResult = cSharpSession.Variable("mark");
 Console.Write(csharpResult);
where CSharpSession is the one from the other tutorial.
It blows up on trying to load the script with a 'value error' but it seems
to me that the definition is correct? Is there something else I need to do?
Cheers, Mark
