What do I have to give in Minecraft so that the wall that I want goes where it should go?

I don't think I'm intelligent enough for that

I want a wall made of glass blocks over there.

I created a flat land world on the iPad

and I need these coordinates

It should start from the ground from the higher block 4

and long it should be from 36 to 76 and

this other coordinate that is displayed first is (width I think) should only be one block wide and is -46

The problem is that I also enter it as it should and so

but then it's not a wall

just a line, so to speak

and I don't know what [tileData: int] and [oldBlockHandling] mean and what I have to enter there

if someone could tell me that was nice

I've googled myself but that didn't help me

/ setblock "block type" x y z (from) x y z (to)

You go to the block where the wall should begin then you stand so that the cross is pointing to the block then you open the chat and type / fill (die korodinate) press enter go to where the wall should end and the cross again the block and open the chat press with the mouse on the previously written command and enter the coordinates welst the block from what the wall should consist of and enter done! There are also great tutorials on Youtube! And actually the XYZ coordinates are shown to you when you write the comand!
