Then, I would suggest it gets bolted into strutils, or sysutils. There are many good reasons to optimize Setlength(), especially for script authors :-)
Currently, I am working (learning) Alpha Controls (alphaskins), and trying to find a fit into FCL/LCL, or Graeme's GUI. And if I tweak too much, things forget to draw - so I understand avoiding "core" bloat. But, Isn't that what SYSUTILs is for :-) Ozz On Wed, Sep 16, 2020 at 11:33 PM J.
