@@@OK@@@ to cancel message box output. The stack will now look like this:
Including input and output in a message box
We could modify the program so that not only the output, but also the input, is
included in a message box. For the case of program
@@@p@@@, the modified
program will look like:
«
“Enter V, T and n: “ {“ :V: :T: :n: “ {2 0} V }
INPUT OBJ→ → V T n
«
V →STR “ ” + T →STR “ ” + n →STR
“ ” + ‘(8.31451_J/(K*mol))*(n*T/V)‘ EVAL “p” →TAG →STR +
+ + MSGBOX » »
Notice that you need to add the following piece of code after each of the
variable names V, T, and n, within the sub-program:
→STR “ ” +
To get this piece of code typed in the first time use:
„°@)TYPE@ @
STR ‚Х ‚л ™+
Because the functions for the TYPE menu remain available in the soft menu
keys, for the second and third occurrences of the piece of code (
→STR “ ”
+ ) within the sub-program (i.e., after variables T and n, respectively), all you
need to use is:
@ STR ‚Х ‚л ™+
