<title>Description</title>
<para>This routine allows to set a variable within a tcl/tk interpreter. When
tcl/tk support is enabled in scilab, this routine can be used to set up
the value of a tcl/tk variable. This can be useful to change some value in
the tcl/tk interpreter without having to build a tcl/tk instruction (and
use <literal>TCL_EvalStr</literal>).</para>
