Create and write records var newRecord = writer.

Before you run an analysis in SPSS, you will be required to code and enter data in SPSS. Code and Enter Data in SPSS Like an Expert. Go to variable view, click an empty row and start defining variables as stated below. Using ( var writer = new SpssWriter( fileStream, variables, options)) In case, you wish to add variables after entering data, you just need to define new variables in the variable view. Using ( FileStream fileStream = new FileStream(' data. Default options var options = new SpssOptions() Set the one special missing value variables. WriteFormat = new OutputFormat( FormatType. PrintFormat = new OutputFormat( FormatType. Create Variable list var variables = new List For original values, use record or record Console. This will get the missing values as null, text with out extra spaces, // and date values as DateTime. Use the corresponding variable object to get the values. Records)ДЇoreach ( var variable in spssDataset. Iterate through all data rows in the file foreach ( var record in spssDataset. Iterate through all the varaibles foreach ( var variable in spssDataset. Create the reader, this will read the file header SpssReader spssDataset = new SpssReader( fileStream) Each case is now associated with a unique identifier. There are a few things you could do to tidy this up for example, get rid of the decimal point and drag the ID variable over to the left so it appears in the first column but really this is job done. You should now be able to create a unique ID number for each of your cases in a SPSS data set.// Open file, can be read only and sequetial (for performance), or anything else using ( FileStream fileStream = new FileStream(' data. The new ID variable contains a unique identifier for each case in the data set. Right, thatвЂ™s it for this quick tutorial. There are a few things you could do to tidy this up вЂ“ for example, get rid of the decimal point and drag the ID variable over to the left so it appears in the first column вЂ“ but really this is job done. The new ID variable contains a unique identifier for each case in the data set. If you press OK, SPSS will generate a variable named ID that will contain a unique identifier for each case in the Data View. The third thing is to drag the $Casenum function into the Numeric Expression box (as per the red arrow above). This will generate a set of unique integers that can function as ID numbers.

This tutorial shows how to define variable properties in SPSS, especially custom missing values and value labels for categorical variables. Variable definitions include a variable's name, type, label, formatting, role, and other attributes.

So, for example, the function will return the number 3 for the third case (normally, but not always, the third row in the Data View), the number 4 for the fourth case, and so on. Written and illustrated tutorials for the statistical software SPSS. The $Casenum variable is just the number of cases read up to and including the current case. This will allow you to select $Casenum in the Functions and Special Variables box. The second thing is to select All in the Function group on the right of the dialog. The first is to specify the name of your target variable in the Target Variable box. There are three things youвЂ™ve got to do to set upВ this box to generate a set of unique identifiers. The Compute Variable dialog box looks like this. WeвЂ™re going to add a variable that will contain a set of number IDs by using the Transform -> Compute Variable menu item. The addition of a variable containing integers functioning as unique identifiers will sort out this issue.

YouвЂ™ll be able to see your new ID variable in SPSSвЂ™s Data ViewДЄs you can see below, we have three variables in our data set, but nothing to distinguish individual cases from each other.

Click on All in the Function Group list, and then drag and drop $Casenum into the Numeric Expression box at the top.

Give your new variable the name вЂњIDвЂќ in the Target Variable box.
