PROBLEM: HOW TO CONNECT OVERTIME RECORDS PLEASE
SAY: you have women all identified by a personal number
When you chose a number, you have all the babies she had over time e.g. a woman had her first child in 2007, the second one in 2009, the third in 2014 and the last one in 2020
If I want to calculate the intervals between pregnancies (and compare with a risk, preeclampsia for example) - What variable should I create? - What command should I do to find: in 2009 the interval with the preceding pregnancy was 21 months, in 2014 the interval with the preceding was 51 months etc....
THANK YOU IF CAN HELP Best

We are changing year, so I am creating a "RU22.REC" with the root RU21.QES file (to replace the RU21.REC one)
1) The other years I went in RU21.CHK and renamed it RU22.CHK and it worked When I do this now, I have 3 pages of errors on CHK (which is exactly the same which works with RU21) quite impossible to correct
2) SECOND OPTION: I went on Epidata analysis and created without any problem RU22.rec Through the procedure SAVEDATA c:\data\RU22.REC. with an automatic transfer of the RU21.CHK to RU22.CHK
BUT IT GIVES ME A VERTICAL QUESTIONNAIRE LIKE A VERY LONG SNAKE, VERY BAD TO MAKE A DATA RECORD
HOW COULD I THROUGH THE "SAVEDATA" PROCEDURE HAVE AN HORIZONTAL (NORMAL) QUESTIONNAIRE
Thank you very much for your help
ALSO: HAPPY NEW YEAR

Have you tried using the .REC file from 1) with the .CHK file from 2)?
Normally, I would have done pretty much the same as you, but like this:
Use the windows command line to copy files, in this order. copy ru21.qes ru22.qes Run EpiData to create ru22.rec from ru22.qes copy ru21.chk ru22.chk

You can do this in Analysis. My example is for the new EpiData Analysis. Similar commands work in classic analysis.
First create your time difference variable new v mois i; // integer variable called MOIS
Then sort the data by subject ID and delivery date sort sujetid accouchment;
Then calculate the time difference between records, but only when the subject ID is the same as in the previous record
mois := iif(sujetid = sujetid[_n - 1], (accouchment - accouchment[_n - 1]) DIV 30, 0);
Dividing the delivery dates by 30 gives approximate months. Dividing by 30.417 and rounding off is more accurate, but I’d go with the integers.
