Store the program back into variable p by using

„@@@p@@@

. Next, run the

program by pressing @@@p@@@. Enter values of V = 0.01_m^3, T = 300_K, and n =

0.8_mol, when prompted. Before pressing ` for input, the stack will look like

this:

After execution of the program, the stack will look like this:

Using a message box

A message box is a fancier way to present output from a program. The

message box command in the calculator is obtained by using

„°L@)@OUT@ @MSGBO@. The message box command requires that the output

string to be placed in the box be available in stack level 1. To see the

operation of the MSGBOX command try the following exercise:

‚Õ~‚t~„ê1.2

‚Ý ~„r~„a~„d

„°L@)@OUT@ @MSGBO@

In summary: The common thread in the three examples shown here is the

use of tags to identify input and output variables. If we use an input string to

get our input values, those values are already pre-tagged and can be easily

recall into the stack for output. Use of the →TAG command allows us to

identify the output from a program.
