Here is the Facform reformatting file, KCTkey.txt:

 

; File: KCTkey.txt

; This converts a BIGSTEPS file into a Facets file

$Input = KCTDAT.txt

$Output = KCTFDT.txt

 

$Facets = 2 ; children and item

 

; labels for the facets

$Flabel = 1, "Children"

$Flabel = 2, "Tapping items"

 

$If=($L=1)

Control="Yes" ; we are processing BIGSTEPS control

Itemnum=0  ; no items so far

$Endif

 

$If=(Control="Yes") ; Processing control variables

; let's pick out the title and write it to the Facets specifications

$If = ($S1W5 = "TITLE")

$Text = $S1W50 ; output the Title=

; and let's also output the other specifications that Facets needs:

$Text = "Output = kctOUT.txt ;the Facets output file"

$Text = "Models = ?,?,D"

 $Endif

 $If = ($S1W4 = "&END")

  Control = "Names" ; set to read item names

$Endif

$Else

 $If= (Control = "Names")

 ; now look for the item names

$If=($S1W9="END NAMES")

Control="Data" ; set to read the data

; print a message to the screen for information

$Print= "Processing END NAMES"

$Else

Itemnum = Itemnum + 1   ; increment the item number

$Label = 2, Itemnum, $S4W20 ; save item number and name

$Endif

$Else

; we are now processing the data - the person name is the identifier

$Label = 1, , $S1W9 ; the element name is person id

; reset item numbering

Item = 0

; now go across the line for as many items as there were names

$Do = Itemnum

Item = Item +1

; the ordinal number of this item

$Label = 2,Item

; the item from its position in the data record: Item 1 in column 11.

$Rating = $S(Item+10)W1 ; output the observation

$Again

$Endif

$Endif
