AutoLisp

I am looking for an AutoLISP program to extract attributes from blocks and create a "Parts List Table".  I guess it would be an ehancement to ATTEXT to count the repeat occurrences and create a table within AutoCAD LT instead of outputting a .txt file.  So, the program would have to extract the following from a block named "sesllc_item callout"

• NO
• VEND
• DESC
• PN

Then count all occurrences of NO and create a QTY column

Any help appreciated!!!

thanks
