Can anyone tell me how to preview calculation stages during program execution. On my HP 42S i used the PAUSE command in my programs. Example of stages:
R=A/P
V=1/n*R^(2/3)*S^.5
Q=A*V
i need to view tagged stage calculation results.
I tried to use the WAIT command but i think i am not using it correctly as it will result in an Error message Bad Argument
