dynamic sql with Pro*C/WinNT 4.0

[Quoted] I'm trying to get some dynamic sql working under Pro*C 2.1.2.0.3 in WinNT 4.0 -- I'm trying to build a dynamic cursor based on user input from a web page. If anyone can help with this snippet of code, I would be very grateful. According to the book I have, this is all I need to build the cursor and retrieve rows... and of course it doesn't work.

void aFunction()
{
  EXEC SQL BEGIN DECLARE SECTION;
   char query[101];
  EXEC SQL END DECLARE SECTION;    SQLDA *descr;

/* database routines to connect... already tested and working */
/* string input gets placed in query */

	EXEC SQL PREPARE S1 FROM :query;
	EXEC SQL DECLARE C1 CURSOR FOR S1;
	EXEC SQL OPEN C1 USING DESCRIPTOR descr;
	EXEC SQL DESCRIBE SELECT LIST FOR S1 INTO descr;
	EXEC SQL FETCH C1 USING DESCRIPTOR descr;
	EXEC SQL CLOSE C1;
