KEYSCR= reassign scoring keys = 123..

This is only needed for complicated rescoring.

Specifies the score values assigned to response choices which match KEY1= etc. To assign responses matching key to the "missing" value of -1, make the corresponding KEYSCR= entry blank or some other non-numeric character.

When XWIDE=1, each value can only take one position, so that only KEY1= through KEY9= can be reassigned. KEY10= through KEY99= can also be used but keep their standard values of 10 through 99.

When XWIDE=2, each value takes two positions, and the values corresponding to all keys, KEY1= through KEY99=, can be reassigned.

Example 1:        Three keys are used, and XWIDE=1.

               Response categories in KEY1= will be coded "1"

               Response categories in KEY2= will be coded "2"

               Response categories in KEY3= will be coded "3"

                       KEYSCR=123 (standard)

Example 2:        Three keys are used, and XWIDE=1.

               Response categories in KEY1= will be coded "2"

               Response categories in KEY2= will be coded "1"

               Response categories in KEY3= will be coded "1"

                       KEYSCR=211

Example 3:        Three keys are used, and XWIDE=2

               Response categories in KEY1= will be coded "3"

               Response categories in KEY2= will be coded "2"

               Response categories in KEY3= will be coded "1"

                       KEYSCR=030201

               or

                       KEYSCR=" 3 2 1"

Example 4:        Three keys are used, and XWIDE=1

               Response categories in KEY3= will be coded "1"

               Response categories in KEY6= will be coded "missing"

               Response categories in KEY9= will be coded "3"

                       KEY3=BACDCACDBA        response keys

                       KEY6=ABDADCDCAB

                       KEY9=CCBCBBBBCC

                       KEYSCR=xx1xxXxx3        scores for keys

               The "x"s correspond to unused keys, and so will be ignored.

The "X" corresponds to specified KEY6=, but is non-numeric and so will cause responses matching KEY6= to be ignored, i.e. treated as missing.

Example 5:        Some items in a test have two correct answers, so two keys are used. Since both answers are equally good, KEY1= and KEY2= have the same value, specified by KEYSCR=. But some items have only one correct answer so in one key "*", a character not in CODES=, is used to prevent a match.

                       CODES=1234

                       KEY1 =23313141324134242113

                       KEY2 =31*324321*3142314***        * is not in CODES=

                       KEYSCR=11        both KEYs scored 1

Example 6:        More than 9 KEYn= lines, together with KEYSCR=, are required for a complex scoring model for 20 items, but the original data are only one character wide.

Original data:        Person name:                columns 1-10

               20 Item responses:        columns 21-40

Solution: reformat from XWIDE=1 to XWIDE=2

       TITLE="FORMAT= from XWIDE=1 to =2"

       FORMAT=(10A1,10X,20A1)        10 of Name, skip 10, 20 of responses

       NI=20

       NAME1=1

       ITEM1=11                        Responses in column 11 of reformatted record

       XWIDE=2

       CODES="1 2 3 4 "                Original response now "response blank"

       KEY1 ="1 2 1 3 2 1 2 3 1 4 3 2 1 1 1 1 1 2 1 1 "        Keying 20 items

       KEY2 ="2 1 2 1 1 2 1 1 2 1 1 1 2 3 3 2 2 * 2 1 "

       ....

       KEY10="3 3 3 2 3 3 4 2 3 * * * 4 4 4 4 4 4 4 4 "

       KEYSCR="1 2 3 2 2 2 3 4 1 4 "        Renumbering 10 KEYn=
