ILFILE= item label file = (after &END)

Useful item identification greatly enhances the output tables. ILFILE= is a list of item labels starting at item 1. Blank lines for unused items. You usually specify items labels between &END and END LABELS in the control file. You may also use ILFILE= for the initial or additional sets of item labels.

 

 

Example: You wish to use abbreviated item labels for the initial analysis, but then switch to longer item labels to produce the final reports.

In your control file specify the shorter labels, one per line,

(a) between &END and END LABELS

or (b) between ILFILE=* and * in the control file

or (c) in a separate file identified by ILFILE=*

 

You can switch to the longer labels, in a file called "Longer.txt" by using the "Specification" menu item, and entering ILFILE=Longer.txt

 

If you have ILFILE= in your control file and your data is also in your control file , be sure that there is an "END LABELS" before your data.

 

Example 1: 4 item arithmetic test with items in ILFILE=*

 NI=4

 ILFILE=*

 Addition  ; labels for the 4 items

 Subtraction

 Multiplication

 Division

 *

 &End

 END LABELS     ; <-   required!

 

Example 2: One set of item labels, then another ....

 NI=4

 &End

 Addition  ; labels for the 4 items

 Subtraction

 Multiplication

 Division

 END LABELS
