Scalar variables are defined with the define
command. As
mentioned above, vectors are defined with the set
command. A
variable may be a number, or a character string. You may use them in
any SM command, by preceding the name of the variable with a
$. For example:
define 2PI 6.283 set x=1,100 do i = 0, 2, .01 { set x[$i] = $i * $2PI } set i=0, 2 , .01 set x=$2PI*i set y = sin(x) limits x y box define xlab {my signal2 xlabel $xlab ylabel sine
