1 Creating Extensive Shift Tables OR How I Learned to Type 1,388,571 wpm! Kelley Weston

2 The goal: Create a format that would consist of all the possible combinations of several values. For example: "M1TM" - "M1TM" = "Missing to 1+ to Trace to Missing"

3 The usual way of accomplishing this: Typing all the combinations into a format. When there are only 4 or 5 possible values in 2 positions, this is no problem.

4 The problem: We are starting with 7 values, in each of 4 positions. This results in 7 * 7 * 7 * 7 = 2401 combinations. The problems include: time ensuring that all possible combinations are accounted for, with no repetitions or omissions accuracy

5 What I need to create:

6 value $CAT_ALL (default = 40 fuzz = 0 min = 1 max = 40 ) "----" - "----" = missing" "---1" - "---1" = "- to 1+" "---2" - "---2" = "- to 2+" "---M" - "---M" = "- to Missing" "---N" - "---N" = "- to None" "---O" - "---O" = "- to Other" "---T" - "---T" = "- to Trace" "--1-" - "--1-" = "- to 1+" "--11" - "--11" = "- to 1+ to 1+" "--12" - "--12" = "- to 1+ to 2+" "--1M" - "--1M" = "- to 1+ to Missing" "--1N" - "--1N" = "- to 1+ to None" "--1O" - "--1O" = "- to 1+ to Other" "--1T" - "--1T" = "- to 1+ to Trace" "--2-" - "--2-" = "- to 2+" "--21" - "--21" = "- to 2+ to 1+" "--22" - "--22" = "- to 2+ to 2+" "--2M" - "--2M" = "- to 2+ to Missing" "--2N" - "--2N" = "- to 2+ to None" "--2O" - "--2O" = "- to 2+ to Other" "--2T" - "--2T" = "- to 2+ to Trace" "--M-" - "--M-" = "- to Missing" "--M1" - "--M1" = "- to Missing to 1+" "--M2" - "--M2" = "- to Missing to 2+" "--MM" - "--MM" = "- to Missing to Missing" "--MN" - "--MN" = "- to Missing to None" "--MO" - "--MO" = "- to Missing to Other" "--MT" - "--MT" = "- to Missing to Trace" "--N-" - "--N-" = "- to None" "--N1" - "--N1" = "- to None to 1+" "--N2" - "--N2" = "- to None to 2+" "--NM" - "--NM" = "- to None to Missing" "--NN" - "--NN" = "- to None to None" "--NO" - "--NO" = "- to None to Other" "--NT" - "--NT" = "- to None to Trace" "--O-" - "--O-" = "- to Other" "--O1" - "--O1" = "- to Other to 1+" "--O2" - "--O2" = "- to Other to 2+" "--OM" - "--OM" = "- to Other to Missing" "--ON" - "--ON" = "- to Other to None" "--OO" - "--OO" = "- to Other to Other" "--OT" - "--OT" = "- to Other to Trace" "--T-" - "--T-" = "- to Trace" "--T1" - "--T1" = "- to Trace to 1+" "--T2" - "--T2" = "- to Trace to 2+" "--TM" - "--TM" = "- to Trace to Missing" "--TN" - "--TN" = "- to Trace to None" "--TO" - "--TO" = "- to Trace to Other" "--TT" - "--TT" = "- to Trace to Trace" "-1--" - "-1--" = "- to 1+" "-1-1" - "-1-1" = "- to 1+ to 1+" "-1-2" - "-1-2" = "- to 1+ to 2+" "-1-M" - "-1-M" = "- to 1+ to Missing" "-1-N" - "-1-N" = "- to 1+ to None" "-1-O" - "-1-O" = "- to 1+ to Other" "-1-T" - "-1-T" = "- to 1+ to Trace" "-11-" - "-11-" = "- to 1+ to 1+" "-11M" - "-11M" = "- to 1+ to 1+ to Missing" "-11N" - "-11N" = "- to 1+ to 1+ to None" "-11O" - "-11O" = "- to 1+ to 1+ to Other" "-11T" - "-11T" = "- to 1+ to 1+ to Trace" "-12-" - "-12-" = "- to 1+ to 2+" "-12M" - "-12M" = "- to 1+ to 2+ to Missing" "-12N" - "-12N" = "- to 1+ to 2+ to None" "-12O" - "-12O" = "- to 1+ to 2+ to Other" "-12T" - "-12T" = "- to 1+ to 2+ to Trace" "-1M-" - "-1M-" = "- to 1+ to Missing" "-1M1" - "-1M1" = "- to 1+ to Missing to 1+" "-1M2" - "-1M2" = "- to 1+ to Missing to 2+" "-1MM" - "-1MM" = "- to 1+ to Missing to Missing" "-1MN" - "-1MN" = "- to 1+ to Missing to None" "-1MO" - "-1MO" = "- to 1+ to Missing to Other" "-1MT" - "-1MT" = "- to 1+ to Missing to Trace" "-1N-" - "-1N-" = "- to 1+ to None" "-1N1" - "-1N1" = "- to 1+ to None to 1+" "-1N2" - "-1N2" = "- to 1+ to None to 2+" "-1NM" - "-1NM" = "- to 1+ to None to Missing" "-1NN" - "-1NN" = "- to 1+ to None to None" "-1NO" - "-1NO" = "- to 1+ to None to Other" "-1NT" - "-1NT" = "- to 1+ to None to Trace" "-1O-" - "-1O-" = "- to 1+ to Other" "-1O1" - "-1O1" = "- to 1+ to Other to 1+" "-1O2" - "-1O2" = "- to 1+ to Other to 2+" "-1OM" - "-1OM" = "- to 1+ to Other to Missing" "-1ON" - "-1ON" = "- to 1+ to Other to None" "-1OO" - "-1OO" = "- to 1+ to Other to Other" "-1OT" - "-1OT" = "- to 1+ to Other to Trace" "-1T-" - "-1T-" = "- to 1+ to Trace" "-1T1" - "-1T1" = "- to 1+ to Trace to 1+" "-1T2" - "-1T2" = "- to 1+ to Trace to 2+" "-1TM" - "-1TM" = "- to 1+ to Trace to Missing" "-1TN" - "-1TN" = "- to 1+ to Trace to None" "-1TO" - "-1TO" = "- to 1+ to Trace to Other" "-1TT" - "-1TT" = "- to 1+ to Trace to Trace"

7 The solution:

8 Lots of Pepsi ® !

9 Let SAS ® create the combinations AND the meanings for them. The Real Solution:

10 The method: 1. Create a data set with the individual values and meanings. This will only consist of a very few records. In our case, we had 7 values. 2. Let SAS create all the combinations and put them into a data set. We will cross the dataset with itself 3 times to create the 4 positions. Remember the Cartesian product? 3. Post-process the dataset to account for baseline and missing values. 4. Create the datasets from which we will create the permanent formats. 5. Write out the permanent formats.

12 Step 2a proc sql; proc sql; create table work.temp as create table work.temp as select x, y from work.temp select x, y from work.temp order by x; order by x; outline outline outline

15 Step 3 data work.temp3 (drop = to_); set work.temp3; %* format these especially for baseline records; if substr(x, 2) EQ '---' if substr(x, 2) EQ '---' then y = scan(y, 1) !!
