  FUNCTION: Returns an expression that has been converted to an Interget subtype.
  SYNTAX: CInt(expression)
  ARGUMENTS: expression is any valid expression
  EXAMPLE: <%
f = "234"
response.write cINT(f) + 2
%>
  RESULT: 236
Converts string "234" to mathematic value 234.
If f is empty (un-initialized variable), cINT() returns 0.
-------------------------------------
  
3. CreateObject()
  FUNCTION: Creates and returns a reference to ActiveX automation object.
  SYNTAX: CreateObject(objName)
  ARGUMENTS: objName is any valid ActiveX automation object.

4. CStr()
  FUNCTION: Returns an expression that has been converted to a variant of subtype String.
  SYNTAX: CStr(expression)
  ARGUMENTS: expression is any valid expression
  EXAMPLE: <%
s = 3 + 2

  EXAMPLE: <%
currentDate = #8/4/99#
newDate = DateAdd("m",3,currentDate)
response.write newDate
%>

<%
currentDate = #12:34:45 PM#
newDate = DateAdd("h",3,currentDate)
response.write newDate
%>
  RESULT: 11/4/99
3:34:45 PM

"m" = "month";
"d" = "day";

If currentDate is in time format then,
"h" = "hour";
"s" = "second";
-------------------------------------
  
7. DateDiff()
  FUNCTION: Returns the number of intervals between two dates.
  SYNTAX: DateDiff(timeinterval,date1,date2 [, firstdayofweek [, firstweekofyear]])
  ARGUMENTS: timeinterval is the time interval to add; date is a valid date expression; firstdayofweek and
firstweekofyear are optional values to specify the first day of the week and first week of year.
  EXAMPLE: <%
