Limits on # of blocks (2000)

If there a limit on the # of blocks that AutoCAD can handle? I have a design
that had 16,000 blocks. Using (old) lisp code I started generating blocks
(lots of them a littlie at a time over several days of work). They all are
created by a lisp function that contains a bunch of entmake commands. The
blocks all contain several user attributes so several entmakes are called in
the function. This code has worked for years. Once the block count in the
database got near 33,000 blocks (over the course of several days) entmake
stopped working! Any ideas?

Thanks

Hmm, 32768 is the maximum value for a 16 bit (2 bytes) integer.
Not sure but it seems like a possible limit.
Check if your block counting variable only can hold a 16 bit value.

I though about a possible 16 bit limit as well. The problem is that I am not
counting blocks in AutoCAD. When this problem started to happen I dumped out
a DXF file and did a count of the number of "BLOCKS" in it. In my lisp code
I do not keep track of blocks. My function simply calls entmake in a loop
to create a compound block then it does a tblsearch to make sure it exists.
If true it inserts the block into the drawing. Today (as a test) I removed
about 10,000 blocks from the database. My (old) code worked fine and I was
able to add ~2000 more blocks. There must be some kind of limit that I am
overlooking.
