CSPRO Applications

2 Creating a Data Entry Application
We’ll now create a data entry application The application will make use of the test dictionary and form Before creating the application, I’ll briefly discuss order of operations in CSPRO data entry path most common data entry commands

3 CSPRO Procedure Types Global procedure (proc global)
logic executed when application begins/ends Form file procedure (proc form_file_name) logic executed before/after each case Level procedure (proc level_name) logic executed before/after level group procedure (proc group_name) logic executed before/after a form or roster variable procedure (proc variable_name) logic executed before/after variable’s field entered

4 Preproc and Postproc Procedures are broken into two parts
logic executed before item for example, skip a variable Postproc logic executed after item for example, check if data entered is consistent for example, skip to a variable If no explicit statement, logic is in the postproc by default

5 Order of Operations Global proc Form file preproc Form file postproc
Level 1 preproc Form 1.1 preproc Field preproc Field postproc ...other form 1 fields Form 1.1 postproc ...other level 1 forms Level 2 preproc Form 2.1 preproc Field2.1.1 preproc Field postproc Form 2.1 postproc ...other level 2 forms Level 2 postproc Level 1 postproc Form file postproc

6 The Data Entry Path The data entry path contains all of the questions that a respondent should be asked It is determined by the type of the questionnaire the responses to questions in conjunction with questionnaire skips questionnaire filters

7 Controlling the Data Entry Path
CSPRO allows one to control completely the data entry path The first step is to open DE application go to options --> data entry select system controlled (while you are there, make all alphanumeric variables upper case)

8 Questionnaire Skips CSPRO has 2 ways of implementing skips
The skip to command if the variable being skipped to is in a single record To skip to a variable or group use skip to variable_name; skip to group_name; The skip to next command if the var. being skipped to is in a multiple record

9 Reentering To force the data entry operator to reenter a field (e.g., if the data entered are inconsistent) use reenter;

10 if command Use to check for a condition: if HH9 <> 1 then
skip to HH16; endif; if not HH6 in 1,2 then reenter;

11 Ending a Level You must manually end a level if
the last variable in the data path is not the last variable on the questionnaire you have entered the last woman or under-five questionnaire This is accomplished using the endlevel command

12 The ENDLEVEL Command The effect of the endlevel command depends upon its context In field/roster/form proc, passes control to the level postproc In level preproc or postproc, passes control to postproc of next highest level In postproc of level 1, pass control to the form file’s postproc

13 Ending a Group A group is a record or roster
A group is ended by the endgroup command The effect of the command depends upon context: In an item procedure, passes control to the current group’s postproc In the preproc of the group, skips the entire group and passes control to the group’s postproc

14 Working Variables Working variables must be declared in the global procedure Numeric working variables can be declared together numeric var1 var2; Alphanumeric working variables are declared separately alpha(length) avar1; alpha(length) avar2;

15 Setting Parameters Global parameters should be declared in the preproc of the forms procedure e.g., minimum age at first birth Assign a value to a working variable created for the purpose Comment your parameter using braces For example minab = 144; {minimum age at first birth in months}

16 Recoding Variables To recode variables, use the recode command
The following logic recodes women’s age into groups recode WM9 => agegrps; => 1; => 2; => 3; endrecode;

17 Generating Error Messages
If the cluster number is invalid, the following code will display an error message errmsg(0010);

18 Providing an Error Message
Error messages must have user-defined text to be effective For the preceding example, one would add a line 0010 cluster number invalid To view the error message file to do so, right click on the message tab while editing a procedure’s logic

19 Error Message Parameters
The values of any variables listed after the error message number will be passed to the error message Parameters are displayed in the error message using %d for numeric values %s for alphanumeric values

20 Creating the Application
Select file --> new Select object type data entry application Use file name: test Use folder: c:\mics\cspro\test Click next Click yes when prompted to use the test form Click finish

21 Modifying the Application
Add logic to check the household number is consistent display message and data entry if not implement the region skip check the date of interview is consistent display message and require reentry if not Compile and then save your application

22 Testing the Application
Click once on execute button on toolbar (traffic light) Use nodata.dat datafile Enter a case
