The commands that define or modify a table will update its descriptor HISTORY. As the length of this descriptor is limited, if you are doing a lot of operations on the same table, you may get a descriptor overflow. In that case you can turn off the automatic addition of history_lines by adding an integer descriptor named HISTORY_UPDA to the table and setting it to 0. <BR><HR> <!--Table of Child-Links--> <A NAME="CHILD_LINKS"> </A> <UL> <LI><A NAME="tex2html1226" HREF="node60.html">Definition of Tables</A> <LI><A NAME="tex2html1227" HREF="node61.html">Displaying Tables</A> <LI><A NAME="tex2html1228" HREF="node62.html">Modification of Tables</A> <LI><A NAME="tex2html1229" HREF="node63.html">Interactive Editing of Tables</A> </UL> <!--End of Table of Child-Links--> <BR><HR> <ADDRESS> <I>Petra Nass</I> <BR><I>1999-06-09</I> </ADDRESS> </BODY> </HTML>
