Only use this if you have too many items to put conveniently on one line of the ISGROUPS= control variable.

 

Instructs where to find the ISGROUPS= information.

GRPFROM=N

       ISGROUPS= is a control variable before &END (the standard).

 

GRPFROM=Y

ISGROUPS= information follows just after &END, but before the item names. It is formatted exactly like a data record. It is helpful to enter "ISGROUPS=", for reference, where the person name would go.

 

Example:        An attitude survey of 10 items with 3 rating scale definitions. Items 1 through 3 on Rating Scale 1, items 4 through 6 on Rating Scale 2 and items 7 through 10 on Rating Scale 3. The ISGROUPS= information is formatted like a data record and entered after &END and before the item names. The responses are in columns 1-10, and the person-id in column 11 onwards.

                       NAME1=11                start of person-id

                       ITEM1=1                start of responses

                       NI=10                        number of items
