Summary:
When TrnDelHistory is performed on a trend, the master file (.hst) increases in size by 240 bytes.  

Solution:
TrnDelHistory no longer increases the size of the trend master file (.hst). CIT has confirmed this to be a problem in Citect for Windows versions 2.XX to 5.30. This problem has been fixed in version 5.31.
