U are knowing the this blockname can be change with the next time open the drawing?

(sssetfirst nil (ssget "_X" '((0 . "INSERT")(2 . "`*U*"))))

Please read about WCMATCH / Wildcards [F1]. You have to quote the * with ` for char compare literally.

And if you are not the creator of Blockreference (command insert) or if we talk about dynamic blocks,

i am sure not all blockreferences you want are refered the same block.

Select all symbols by hand and check there Blockname in properties palette CTRL+1,

is ther one name (*U27) or *varies*?

Place a reverse quote before the aterisk so that the filtering treats the asterisk as a character, not a wildcard.

'(`*U27)

Hi,

Good Day!!

Your help in this highly appreciated. but i using Following code

(sssetfirst nil (ssget "_X" '((0 . "INSERT")(2 . "`*U27*"))))

but code will select other 2 -3 Block at the same time.

but selected block name is different (U270, U275 , U274) as per my attach  jpg. file.

So how i select particular single Block ? as per above lisp code. 

can we do one thing,  select single Block Automatically on screen by Block Name ("U27") and Block Layer Name ("Left View-Support") Through Lisp code from entire Drawing.

Your help in this highly appreciated.

You didn't commented my comments above.

I wrote about where you can read about WILDCARDs in AutoCAD: F1 - wcmatch 

About DXF-codes too: Click - Groupcode 8 is for Layer

(sssetfirst nil (ssget "_X" '((0 . "INSERT")(2 . "`*U27")(8 . "Left View-Support"))))

get

INSERTs

only of BLOCK "*U27"

only on Layer "Left View-Support"
