This does not answer my question as the article only deals with using variables on the stack.

 

I want to have a number or piece of text  left on the stack after a HP Prime program has terminated and that number or piece of text was stored in a variable during the execution of the program.

The last return value of whatever is in the program will be returned, as will "return" begin called earlier in a program.

 

Only a single value of any type may be returned.

 

EXPORT MyFunction(a)

BEGIN

    IF(a==1) RETURN "a is one";

    "a not 1"

END;

TW:

 

Your sample program came up with an error so I changed it to:-

 

EXPORT MyFunction(a)
BEGIN
IF(a==1) THEN
RETURN "a is one";
ELSE
RETURN "a not 1";
END;
END;

 

to get it to run.

 

When it runs it displays either "a is one" or "a is not one" in a display box in the centre of the screen, but nothing is returned to the stack (which is what I want).

 

Any ideas on this?

When you run a program from the program catalog, it pacakges the restult automatically since there is no where for the result to "go".

 

Call your function from the RPN stack, and the result goes there.
