Program takes in variable non exact.

It will be in variables->CAS-> <there>

One difference between the way that the CAS system handles things is that all objects are "variables". To the cas, a program function you made is essentially identical to storing a number into 'x'. They both are variables, that contain something. In the case of the little function, it is a small set of commands that execute steps.

When you use the #cas #end stuff, you are actually telling the program compiler "execute the things I'm typing within this block as if I typed them on the CAS screen". If you do something like myfunc(x,y):=x+y on the cas screen, you get a variable named myfunc, that contains a function taking two arguments. Note that is you delete/remove/rename your function that was created in your program, it could disappear unexpectedly. To "get it back", opening the program file, then exiting it again would then reexecute those commands and make the CAS variable again.
