  ...
  end

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.
