DATA= name of data file = (data at end of control file) |
Your data can be the last thing in the control file (which is convenient if you only have a small amount of data), but if you have a large amount of data, you can place it in a separate file, and then use DATA= to say where it is. FORMAT= reformats these records. MFORMS= enables multiple reformatting.
DATA= file name |
file containing details |
DATA = file name + file name+ ... |
multiple data files |
DATA = ? |
opens a Browser window to find the file |
Example 1: Read the observations from file "A:\PROJECT\RESPONSE.TXT".
DATA=A:\PROJECT\RESPONSE.TXT
Example 2: Read scanned MCQ data from file DATAFILE.txt in the current directory.
DATA=DATAFILE.txt
You may specify that several data files be analyzed together in one run, by listing their file names, separated by "+" signs. The list, e.g., FILE1.TXT+MORE.TXT+YOURS.D, can be up to 200 characters long. The layout of all data files must be identical.
Example 3: A math test has been scanned in three batches into files "BATCH.1", "BATCH.2" and "BATCH.3". They are to be analyzed together.
DATA=BATCH.1+BATCH.2+BATCH.3
