Let's see some examples based on this command.

Example 1:
     foreach a 1:5
        echo $a
     end

Output:
     
    gnucap> 1
            2
            3
            4
            5

Example 1:
     param a=2
     foreach val 2:4
        eval($val+a)
     end

Output:
     gnucap> (2+a)=4.
             (3+a)=5.
             (4+a)=6.
