Press @@@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: " {" :n: " {2 0} V } INPUT
«
:V: :T:
STR " " + T STR " " + n STR " " +
«
OBJ V T n V
'(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:
„°@) T YPE@ @ STR ‚Õ ‚ë ™+
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 ‚Õ ‚ë ™+
