Section 2 - Calculating Distance

Distance_Done is a truth state that varies.
Stepscounter is a number that varies.

To calculate minimum Distance between (Start - a thing) and (Finish - a thing):
If location of Start is location of Finish
begin;
Change Stepscounter to 0;
Change Distance_Done to false;
If Start is not connected with Finish
begin;
If Start is straight of Finish
begin;
If Start is below of Finish
begin;
Change Stepscounter to X-Axis of Start;
decrease Stepscounter by X-Axis of Finish;
decrease Stepscounter by 1;
end if;
If Start is above of Finish
begin;
Change Stepscounter to X-Axis of Finish - 1;
decrease Stepscounter by X-Axis of Start;
end if;
Change Distance_Done to true;
end if;
If Distance_Done is false
begin;
If Start is on a sector right of Finish
begin;
If Start is below of Finish
begin;
Change Stepscounter to X-Axis of Start;
decrease Stepscounter by X-Axis of Finish;
decrease Stepscounter by 1;
end if;
If Start is above of Finish
begin;
Change Stepscounter to X-Axis of Finish - 1;
decrease Stepscounter by X-Axis of Start;
end if;
Change Distance_Done to true;
end if;
end if;
If Distance_Done is false
begin;
If Start is on a sector left of Finish
begin;
If Start is below of Finish
begin;
Change Stepscounter to X-Axis of Start;
decrease Stepscounter by X-Axis of Finish;
decrease Stepscounter by 1;
end if;
If Start is above of Finish
begin;
Change Stepscounter to X-Axis of Finish - 1;
decrease Stepscounter by X-Axis of Start;
end if;
Change Distance_Done to true;
end if;
end if;
If Distance_Done is false
begin;
If Start is indirect neighbour of Finish
begin;
choose row with Letters28 of Y-Axis of Start in Table 200;
Change tmp to Number Entry;

If tmp > Number Entry
begin;
Change Stepscounter to tmp;
decrease Stepscounter by Number Entry;
decrease Stepscounter by 1;
end if;
If tmp < Number Entry
begin;
Change Stepscounter to (Number Entry - 1);
decrease Stepscounter by tmp;
end if;
Change Distance_Done to true;
end if;
end if;
If Distance_Done is false
begin;
If Start is left of Finish
begin;
choose row with Letters28 of Y-Axis of Start in Table 200;
Change tmp to Number Entry;
choose row with Letters28 of Y-Axis of Finish in Table 200;
If Start is above of Finish
begin;
Change tmp_X to X-Axis of Finish;
Decrease tmp_X by X-Axis of Start;
Change tmp to (Number Entry - tmp);
If tmp > tmp_X, change Stepscounter to (tmp - 1);
If tmp < tmp_X, change Stepscounter to (tmp_X - 1);
If tmp is tmp_X, change Stepscounter to (tmp_X - 1);
end if;
If Start is below of Finish
begin;
Change tmp_X to X-Axis of Start;
Decrease tmp_X by X-Axis of Finish;
Change tmp to (Number Entry - tmp);
If tmp > tmp_X, change Stepscounter to (tmp - 1);
If tmp < tmp_X, change Stepscounter to (tmp_X - 1);
If tmp is tmp_X, change Stepscounter to (tmp_X - 1);
end if;
Change Distance_Done to true;
end if;
end if;
If Start is right of Finish
begin;
choose row with Letters28 of Y-Axis of Finish in Table 200;
Change tmp to Number Entry;
choose row with Letters28 of Y-Axis of Start in Table 200;
If Start is above of Finish
begin;
Change tmp_X to X-Axis of Finish;
Decrease tmp_X by X-Axis of Start;
Change tmp to (Number Entry - tmp);
If tmp > tmp_X, change Stepscounter to (tmp - 1);
If tmp < tmp_X, change Stepscounter to (tmp_X - 1);
If tmp is tmp_X, change Stepscounter to (tmp_X - 1);
end if;
If Start is below of Finish
begin;
Change tmp_X to X-Axis of Start;
Decrease tmp_X by X-Axis of Finish;
Change tmp to (Number Entry - tmp);
If tmp > tmp_X, change Stepscounter to (tmp - 1);
If tmp < tmp_X, change Stepscounter to (tmp_X - 1);
If tmp is tmp_X, change Stepscounter to (tmp_X - 1);
end if;
end if;
otherwise;
Change Stepscounter to 0;
