Help asked: systemRPL ^IFMain question

Thanks for posting your code snippet, it helped to better understand what you are attempting to do.

It appears to me that you may be running into trouble by making the call to ^IfEnterKeyPress in an effort to simulate the ENTER key while an EditLine is active. I believe that procedure was designed more for other situations where you might want to do some of your own processing as a result of responding to a message, then simulating the effect of the user pressing the enter key. There's a subtle difference in context here.

The following may work better for you:

Immediately after the TakeOver in your menu routine, test for the presence of an active EditLine and take care of storing the current value if there is one. Then proceed with your calculations as needed. Here's a sample of what that might look like (with absolutely no error checking!):

Code:

TakeOver
EditLExists? IT ::
   EDITLINE$ DOSTR>                    ( Get the current edit string and parse it )
   FLASHPTR IfSetCurrentFieldValue     ( Set the value obtained as the current field value )
   InitEd&Modes                        ( Clear the current EditLine )
;

( ... further processing as needed for menu command ... )

This assumes, of course, that I've understood what you're trying to accomplish. I may have misunderstood your intent.

If it helps to see a more complete example, here's the generated source code from an InputForm built using Debug4x. This is about as simple an example as I could think of to show how the code might work. In this case, the "SUM" menu command simply adds the three values in fields 1-3 and places the total into field 4. I'm hoping this works the way you want:
