Copying two or more variables using the stack in RPN mode

The following is an exercise to demonstrate how to copy two or more variables

using the stack when the calculator is in RPN mode. We assume, again, that

we are within sub-directory {HOME MANS INTRO} and that we want to copy

the variables R and Q into sub-directory {HOME MANS}. The keystrokes

necessary to complete this operation are shown following:

‚@@ @R@@ ³@@@R@@ `

‚@@ @Q@@ ³@@@Q@@ `

„§K K

To verify the contents of the variables, use ‚@@ @R@ and ‚@@ @Q.

This procedure can be generalized to the copying of three or more variables.

Reordering variables in a directory

In this section we illustrate the use of the ORDER command to reorder the

variables in a directory. We assume we start within the sub-directory {HOME

MANS} containing the variables, A12, R, Q, z1, A, and the sub-directory

INTRO, as shown below. (Copy A12 from INTRO into MANS).

Algebraic mode

In this case, we have the calculator set to Algebraic mode. Suppose that we

want to change the order of the variables to INTRO, A, z1, Q, R, A12.

Proceed as follows to activate the ORDER function:

„°˜@@OK@@ Select MEMORY from the programming menu

˜˜˜˜ @@OK@@ Select DIRECTORY from the MEMORY menu

—— @@OK@@ Select ORDER from the DIRECTORY menu

The screen will show the following input line:

Next, we’ll list the new order of the variables by using their names typed

between quotes:

„ä ³)@INTRO ™‚í³@@@@A@@@

™‚í³@@@z1@@™‚í³@@@Q@@@™

‚í³@@@@R@@@ ™‚í³@@A12@@ `

1 2 ... 114 115 116 117 118 119 120 121 122 123 124 ... 886 887
