I suspect -2.41704E-35 is a "junk" value -- i.e. you are printing out an uninitialized variable. In most BASIC's, there is *NO* retention from line to line when you enter them as single line commands. So, entering E=1 on one line, and then entering PRINT 4 * E on another line, will only get you an uninitialized variable. BASIC doesn't remember the E=1 part at that point. To do what you want, you'll have to figure out what the continuation character is (maybe ";" ???) for your particular flavor of BASIC, and then enter E=l ; PRINT 4*E all on one line. You get the idea. OR, you could do what was already suggested, and enter it in all in a program, and then "RUN" the program.
Hope this helps.
