Checking variables contents The simplest way to check a variable content is by pressing the soft menu key label for the variable. For example, for the variables listed above, press the following keys to see the contents of the variables: Algebraic mode Type these keystrokes: J@@z1@@ ` @@@R@@ `@@@Q@@@ `. At this point, the screen looks as follows: RPN mode In RPN mode, you only need to press the corresponding soft menu key label to get the contents of a numerical or algebraic variable. For the case under consideration, we can try peeking into the variables z1, R, Q, A12, α, created above, as follows: J@@z1@@ @@@R@@ @@@Q@@ @@A12@@ @@»@@ At this point, the screen looks like this: Using the right-shift key followed by soft menu key labels In Algebraic mode, you can display the content of a variable by pressing J@ and then the corresponding soft menu key. Try the following examples: J,@@p1@@ , @@z1@@ , @@@R@@ ,@@@Q@@ , @@A12@@ NOTE: In RPN mode, you don't need to press @ (just J and then the corresponding soft menu key.) Page 2-13
