How do I ...? with Maple (Student)

Hi my dear friends,

I’ve developed a simple procedure as follows:

> PS:=proc(E)

> if E<10 then E^2

> else 0

> end if:

> printf("V=%d\n",%):

> end proc:

I want to write a command that after Entering the >PS:=proc(E) tells users a statement like this: “Please Enter Energy in SI Units as E in this command >PS(E)” immediately after >end proc: .

How can I do it?

Thanks a lot in advance for your precious helps,

Werner Melzer

readstat or Maplet

You could use readstat command, but it is better to write a simple Maplet for such a sort of an interaction.

> PS := proc ()

local E;

 E := readstat("Enter the value of E :");

 if E < 10 then E:=E^2 else E:=0; end if;

 printf("V=%d\n", E);

 end proc;
> PS();
