Date/ Date Range Selection
Dear Jamie, Thanks for the effort and time.
I tried the TRUE FALSE option instead of Y and N , no luck.
The examples you provided, were for European date format <dd/mm/yyyy> Actually the applications developed in EPI6 were running for many years. EPI6 liked <mm/dd/yyyy> format. So the data entered over many years had actually American <mm/dd/yyyy> format.
I defined a new variable , AATDATE2 <dd/mm/yyyy> format, copied and converted American dates data to <dd/mm/yyyy>.
Your last suggestion PQ= (ATTDATE2 >=DMY(1,1,2006) AND (ATTDATE2 <=DMY(30,3,2006) worked then.
Epi Analysis does not feel comfortable with American date format. I am not professional programmer but still strongly feel that date/ date range selection should be simple and intuitive.
Rather than posting fresh message, I request you to kindly help to solve following two queries also;
1.What is the EPI ANALYSIS equivalent of EPI6 command SET
PROCESS=BOTH. EPI ANALYSIS processes only undeleted records.
2. While running long PGMs in EPI ANALYSIS, if no records are selected after a select condition, the programme aborts. The rest of the commands of the PGM are not processed. You might remember, EPI6 could run PGMs of any length, closing database, recoding, erasing and writing new .rec files easily.
Jens and his Epidata Team have done a marvelous job of preserving the functionality of EPI6. May be few fine tuning are still required in this good effort.

Hi Shavindar,
When I tested, this ATTDATE was defined as <mm/dd/yyyy>. I'm using the latest build of Analysis and it has no problem with the comparisons between ATTDATE defined this way and dmy(1,1,2006) function. What is the Build # at the top of the Analysis screen?
To process deleted record, use the following before you READ SET READ DELETED=ON
I've never tried it.
