In the command line (as well as in a batch file), you need to provide
the entire loop "in one line". That is, you need to use & to put all
the lines of your loop into one, as in:

for i=0,1 do begin & print,i & print,i & endfor

But that is only proper for something short, like two or three short
statements in the loop. Do not abuse it. If you need to write a long
block it should not be done in this way, it should be in a function or
procedure.
