It skips the second for loop because 1 is less than 20 and because it's decreasing.
In a regular for loop, the first number must be less than the second. In a decreasing for loop, the first number must be greater than the second.
You have a decreasing for loop in which the first number is less than the second. Switch them.

you also need to make the 1st for loop start at 1.. since u used locate (x,y) and the x is the for loop that starts at 0, and there is no row 0, so it needs to start at 1

if u want, use locatexy
and yes, whenever turing sees a decreasing thats the other way, it will automatically stop/ 8)

so the code would be

code:

for x : 1 .. 20     for decreasing y : 20 .. 1         locate (x, y)         put x     end for end for

but if u wanted the numbers to start at 0, you would have to do this

code:

for x : 1 .. 21     for decreasing y : 20 .. 1         locate (x, y)         put x - 1     end for end for
