simple question about plotting

[Vitaliy A Repin]

Hello!

What should I do if I want to plot special function, such as besselj(1,x)?
Should I do something like the following:

while (x<8)
Y(i)=besselj(1,x);
X(i)=x;
x=x+.1;
i=i+1;
endwhile;

plot (X,Y)

?

It seems to me, it is the ugly solution.

Good-bye!
