What is SYSOBJECTS.tbl

[Thunderstone]

Hello,

I am trying to gain a better understanding of the search form and saw the
lines
<sum "%s" $dbdir "/SYSOBJECTS.tbl">
<apicp eqprefix $ret>
<sum "%s" $dbdir "/USROBJECTS.tbl">
<apicp ueqprefix $ret>

I was unable todo a sql select on these tables and was wondering if you
could explain what they are used for?

Sysobjects is a private table to the Texis software and
cant be searched with <sql>
