I think that its better to edit the block then atta atribute in it then ATTSYNC the block then use this lisp to renumber the attribute.

DONOT forget to delete the old text
its easy bono25, but i think you're going about it the wrong way. why not use one attribute block. instead of re-defining all 250 of them.
Can you explain this line ..
The TEXT and BLOCK are a separate entities? or the TEXT is already a part of the block?
I see, and i suppose the TEXT entities are not always on the same spot in relation with the block? then you really need to do the transformation one by one, but then again, use one (1) attribute block.
Redefine the block [250 blocks with the same name.] to include the attribute entity.
Use a code to copy TEXT string to attribute.
