How To Retrive A SP Table Inside A SP?

Hello, inside of my SP i want to execute another SP, something like:

EXEC [dbo].[Forum_DeleteBoard] @BoardID = @DelBoardID

this function Forum_DeleteBoard returs one row with 3 columns as a table, how do i get the first column of that table into a variable so i can check if it was ok or not
(it returns just one row with 3 columns).

Columns it returns:
QResult , Threads , Answers

SELECT @isok = QResult FROM EXEC [dbo].[Forum_DeleteBoard] @BoardID = @DelBoardID   ?

or how do you get it?
