Purpose: dowhile statement is similar to while loop except the condition is tested after the statements are executed.
Status: Done. Nesting is not supported at the moment.
Syntax:
dowhile condition ... end
Let's see some example of dowhile statement
Example 1:
   param a=3
   dowhile a<3
      eval(a)
   end
Output:
gnucap> a=3.
Example 2:
   param a=3
   dowhile a>1
     eval(a)
     echo after decrement
     measure a eval(a-1)
   end
Output:
    gnucap> a= 3.
            after decrement
            a= 2.
            a= 2.
            after decrement
            a= 1.
