Movable airship to drive

[Ghostfish_]

Hello, how to turn text into a block? I think I saved all blocks' name in text instead of alias, here is the example:

set block at {_workingLoc.%player%} to "stone" #won't work
set block at {_workingLoc.%player%} to stone #instead this will work

Is there any way to do it? Thanks

Oh by the way, how to copy the whole block information and paste in skript, I want to move the command block with the identical command
Tried worldedit and /clone, they work but they will pop up the useless messages to me.
Tried skript-mirror, here is the code:

import:
    org.bukkit.Location

command //m:
    trigger:
        set {_blockOld} to {locS1Java}.getBlock()
        set {_blockNew} to {locS2Java}.getBlock()
        {_blockNew}.setTypeIdAndData({_blockOld}.getTypeId(), {_blockOld}.getData(), true)
        set {_world} to player.getWorld()
        set {_tileEntityOld} to {_world}.getTileEntityAt({locS1Java}.getBlockX(), {locS1Java}.getBlockY(), {locS1Java}.getBlockZ())
        set {_tileEntityNew} to {_world}.getTileEntityAt({locS2Java}.getBlockX(), {locS2Java}.getBlockY(), {locS2Java}.getBlockZ())
        set {_we} to {_world}.getHandle()
        {_we}.setTileEntity({_tileEntityNew}.getPosition(), {_tileEntityOld})

This will work, but it can't delete the old command block. As soon as the old one got deleted, the new one lose the command it should carry

Other things emmm.....
the current algorithm is whether spawn falling blocks or delete and create blocks. Well, I think both of them are heavy for the server. need some advice (except stop doing the whole program) haha.

Thanks, guys!
