Singular Manual: for

  | ### 5.2.8 for `Syntax:` `for (` init_command`;` boolean_expression`;` iterate_commands`)` block `Purpose:` repetitive, conditional execution of a command block. The command init_command is executed first. Then boolean_expression is evaluated. If its value is TRUE the block is executed, otherwise the `for` statement is complete. After each execution of the block, the command iterate_command is executed and boolean_expression is evaluated. This is repeated until boolean_expression evaluates to FALSE. The command `break;` leaves the innermost `for` construct. `Example:`
      // sum of 1 to 10:
      int s=0;
      for (int i=1; i<=10; i=i+1)
      {
         s=s+i;
      }
      s;
      ==> 55
