[EpiData-list] In analysis

Dear Sir Greetings

Kindly tell me some examples about select date variable

I have variable in which i stored the date in (dd/mm/yyyy) format.

but in analyis i use select command to selecting the date it does not work.

I type the SELECT SYNATX LIKE THAT on command prompt

MY DATE VARIABLE IS - A39 THIS VARIABLE TYPE IS (DD/MM/YYYY)

SELECT A39 > "10/10/1959" ----------------------------- IT GIVES THE MESSAGE INCOMPATIBLE STRING VARIABLE . BUT IN EPINFO -60.4 IT WORKS VERY GOOD.
