I wish there was a good way. Pre-padding is one way, but, I think you still need exclusive access. Here's an example of using a memo without growing it:

CREATE TABLE c:\temp\test (Mem M)
APPEND BLANK
REPLACE Mem WITH SPACE(100000)  && pre-allocate
FOR i = 1 TO 1000
  REPLACE Mem WITH STUFF( Mem,  1+ 100 * (i-1), 100, PADR( REPLICATE( TRANSFORM( i), 100), 100))
ENDFOR
USE

>I need a small adjustment in this recycle approach. Basically, it recycles. It's just that the memo file keeps increasing. I can't seem to find what I'm missing here.
