Solution

Solution Let us assume that you want to distinguish between the time before November 7, 2001, and after. GuiXT only knows how to compare a variable with a value:
if V[variable=value]

The value can also be the content of a 2nd variable:

if V[variable=&[variable2]]

It is necessary to use the date format “year month day”, since GuiXT converts each string into a number before comparing it with “<” or “>”. So you can use the command

if V[variable>&[today_ymd]] 
if the variable contains a date in format ymd.

// Sample coding 
Set V[NewDate] “20011107″
if V[NewDate>&[today_ymd]]
  Title “before today”
else
  Title “today, or later”
endif

If the date field has a different format,  e.g “d.m.y” like 22.04.2002, you can use string functions in order to obtain the right format: 

// F[Date] contains a date in format d.m.y

set V[NewDate] “&F[Date](7-10)&F[Date](4-5)&F[Date](1-2)”
if V[NewDate>&[today_ymd]]
  Title “before today”
else
  Title “today, or later”
endif

Note: As of GuiXT version 2003 Q1 9, direct date comparisons and calculations are possible, see Tip 14 for an example.
