Jumps in Epidata Entry
by epidata-list＠lists.umanitoba.ca 15 Jul '26

Dear list, I have two questions regarding Jumps in EpiData Entry. 1) I want to jump to variable v10 if de score for v8 is 1 to 7. Of course this works: v8 RANGE 1 9 COMMENT LEGAL USE oplcat JUMPS 1 v10 2 v10 3 v10 4 v10 5 v10 6 v10 7 v10 END MUSTENTER END Is a shorter syntax possible and if so, how? 2) Is it possible to make a jump defination that depends on the value entered in a previous question? For example: After entering the value for variable v5 I want to jump to v8 if the answer on question v3=1. Kind Regards, Pieter van Groenestijn The Netherlands

fill fields from COMMENT LEGAL file
by epidata-list＠lists.umanitoba.ca 15 Jul '26

15 Jul '26

I'm studying the copydata example to learn how to extract several variables from a file identified in a COMMENT LEGAL statement. In A3.chk, the statement "TYPE COMMENT atransfer" appears. What is atransfer? I don't see where it has been defined as a variable and I don't find it as a system variable. Further, the program seems to be parsing the string in atransfer according to the position of punctuation. Where is the format of this string defined? Perhaps to be a bit more explicit: I have file with a list of CHWs: District, Village, CHW name and a survey conducted by the CHWs. As the data is entered for the survey, I'd like to present pick lists to facilitate entry. The data is quite strictly hierarchical: Villages occur within Districts, an CHWs live in villages. Thank you,

RE: EpiData-list Digest, Vol 130, Issue 7 - count number of records

Hi Walter, You could create a count of the number of records per unique individual and then select the first record: Sort idunique visitdate gen i count = 1 Var Name count of type Integer and length: 9 decimals 0 if idunique = idunique[_n-1] then count= count[_n-1] + 1 count= count[_n-1] + 1 the [_n] indicates recnumber and by subtracting one "_n-1" we get the previous record select if count=1 Hope this helps, Renate -----Original Message----- From: epidata-list-bounces(a)lists.umanitoba.ca [mailto:epidata-list-bounces@lists.umanitoba.ca] On Behalf Of epidata-list-request(a)lists.umanitoba.ca Sent: Monday, September 29, 2014 1:01 PM To: epidata-list(a)lists.umanitoba.ca Subject: EpiData-list Digest, Vol 130, Issue 7 Send EpiData-list mailing list submissions to epidata-list(a)lists.umanitoba.ca To subscribe or unsubscribe via the World Wide Web, visit http://lists.umanitoba.ca/mailman/listinfo/epidata-list or, via email, send a message with subject or body 'help' to epidata-list-request(a)lists.umanitoba.ca You can reach the person managing the list at epidata-list-owner(a)lists.umanitoba.ca When replying, please edit your Subject line so it is more specific than "Re: Contents of EpiData-list digest..."

Since the data are sorted first by id and then visit, this will leave vfirst=1 whenever id changes.

SV: [EpiData-list] Epidata Manager key unique handling
by epidata-list＠lists.umanitoba.ca 19 Sep '14

All you have to do, is to define a key, which you find under project properties. After definition of a key, only one observation can be entered for each value. In entryclient a key is always what was "key unique" in Classic Epidata 3.1.

Dear Epidata users I am facing a problem transferring a field value from a parent file to a child file. In the parent file I have initial SRQ (srqinit) and I want the same value to appear in the chiled file. I did the following: In the parent file before file Define Gsrqinit ## Global srqinit MUSTENTER AFTER ENTRY LET Gsrqinit=srqinit END END In the child file BEFORE RECORD srqinit=varsrqinit END However, this doesn't seem to work. Your help will be most appreciated. Mohammed -- *---------------------------------------------------------*

Relational database
by epidata-list＠lists.umanitoba.ca 09 Sep '14

09 Sep '14

Hi there I have created a relational database for two files. A pre-entry data file (parent file) and an intake file (child file). the relate command is working well. However, when finishing information entry in the child file and go back to the main file using F10 , EpiData doesn't take me automatically to a new parent file but to the previous file and a new parent file will only open when using the navigation bottom. Also when I fill in the second parent file and automatically move to the child file, I found the information entered for the previous child file. Hope you can help me solving this problem Thanks Mohamed -- *---------------------------------------------------------*
