Merging three attribute blocks into one without loosing the information already entered

[Dean.Horvath]

I have a situation where there are 3 attribute blocks in old titleblocks. Title, Revisions, and References.

I would like a to have a lisp that would combine the three attribute blocks into one without loosing the information already entered. The reason I would like a lisp is there are hundreds of Titleblocks to update.

There use to be in an older version of AutoCAD under express tools a way to do this that is no longer there however a lisp can do multiple drawings when batched instead of one at a time. All the drawing are consistent in the names for the three attribute blocks so there is no need for selecting the blocks manually.

So simplest is read Title, Revisions, and References. Then strcat and put answer in say Title, set the others to nothing or a Space. Is this ok idea ? Or is the title block to actually change its look ?
