[Jprogramming] Getting J to work with .NET

Fri Jul 9 20:53:07 HKT 2010

I wrote a wrapper function for that, so you can just do:
 var session = new Session();
 session.Eval("result=: 2 + 2");
 var result = session.Variable("result");
 Console.Write(result);
 session.Load("C:\samplescript.ijs");
but it's essentially the same as what Raul is suggesting:
 /// <summary>
 /// Loads an external script into the current J session
 /// </summary>
 /// <param name="fileName">Complete path and filename to the script to be loaded</param>
 public void Load(string fileName)
 {
 string script;
 // Assign the filename to a J variable
 this.Variable("script2load",fileName);
 // Check if were in debug mode first.
 if (this.debug)
 {
 // Were debugging so we show what were loading and stop on error
 script = "0!:001 < script2load";
 }
 else
 {
 // Not debugging, dont need to show script
 script = "0!:0 < script2load";
 }
 // Now evaluate the script.
 this.Eval(script);
 }

session.Eval("0!:0<'script.ijs'");
ought to work
Or, if you want a dynamic name, use a variable to identify the script.
