  begin
    sSource := "SessionIDTest.asp?SessionID=SID8:44:43&amp;"
               "Param2=Value2";
    sRegex := "SessionID=\(SID[0-9:]+\)";
    write("source = "+sSource); writeln;
    write("regex = "+sRegex); writeln;
    StrRegexCompile(hRegex, sRegex);
    match := StrRegexExecute(hRegex, sSource);

    if match then
      StrRegexSubst(hRegex, "\1", sTarget, STRING_COMPLETE);
      write("match: "+sTarget); writeln;
    else
      write("no match"); writeln;
