You can pass in an stEval and it will be copied to the list:

	// stringEval is a local variable

	stEval stringEval;

	// set the type and value of the stEval

	stringEval.type = ST_STRING;
	STSTRING(stringEval) = "some text";

	// set retain to 1, unless the memory for the text has
	// been allocated by "slMalloc"

	stringEval.retain = 1;

	// add the string to the list.  the list will COPY the
	// string, so we can now reuse, or disregard stringEval

	stEvalListAppend(list, &stringEval);
