Using FILE TYPE GROUPED
To use FILE TYPE GROUPED to define a grouped file, each record must have a case
identifier and a record code. In the following commands, each data record contains a
student ID number coded 1, 2, or 3 and a code indicating whether the score on that
record is a reading (R), math (M), or science (S) score:
FILE TYPE GROUPED RECORD=#REC 3(A) CASE=STUDENT 1.
RECORD TYPE ’R’.
DATA LIST / READING 5-6.
RECORD TYPE ’M’.
DATA LIST / MATH 5-6.
RECORD TYPE ’S’.
DATA LIST / SCIENCE 5-6.
END FILE TYPE.

LIST.
• FILE TYPE indicates that data are in grouped format. RECORD defines the variable
containing record codes as string variable #REC in column 3. CASE defines the case
identifier variable STUDENT in the first column of each record.
• One pair of RECORD TYPE and DATA LIST statements appears for each record type
in the file. The program reads reading score in every R record, math score in M
records, and science score in S records.
