RE: Date variable

Hi! The 3 variables (Day, Month and Year) have to be string (or at least, it works that way!) Assuming following variable names : Date: DATE, Day: DAY, Month: MONTH, Year: YEAR) In the After entry block of the date variable, place the lines below: DAY = day(DATE) MONTH = month(DATE) YEAR = year(DATE) Day, month and year are functions which automatically extract the corresponding values. Note: besste to create string variables, so days / months < 10 will stay the way thay have been entered, (03 will wtay 03 and not 3).

Why is this necessary? I see "LION", upper case and delineated with " ".

Dear Colleagues, As I was using EpiData, I was impressed because it is simple to understand and even train someone on how to use it. However, I was challenged on how to revise a questionnanire and effect the revision into the record file. If you know how to do it, just direct me. I will be happy for your quick response.

How to select "string variables" in Epidata Analysis ?
by epidata-list＠lists.umanitoba.ca 01 May '05

01 May '05

Dear sir, Hello. I am one of Epidata Users around the world. I can not select "string variables" by Epidata Analysis. I am not sure whether the "Epidata Analysis" program can select string variables. For example: Name of my Variable : Outcome and my Options for the variable : cure , death , disabled, unknown I write(or do) the command: select outcome="death" But no selection is done and this is the massage : No records available But I am sure that records are available because I myself have entered them and also EpiInfo software do select them ! Thank you REZA __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
