How do I split a specific list in a column into individual items?
Let's say I have the columns Time and Greetings, and I want to split whatever is in Greetings for Time = PM.
Assume you don't know how many items will be on the list - greetings for PM could be 1, 2, 3, 4, 5+ etc. items long
Whatever is in Greetings is being referenced by another variable i.e. For PM, list in Greetings is from &PM_items.
where &PM_items. contains "Bye", "Adios", "Goodbye", "See you" - though these items can change.
Before:
Time Greetings
AM "Hello", "Hi", "Good morning"
PM "Bye", "Adios", "Goodbye", "See you"
Any "How are you"
After:
Time Greetings
AM "Hello", "Hi", "Good morning"
PM1 "Bye"
PM2 "Adios"
PM3 "Goodbye"
PM4 "See you"
Any "How are you"
/* Maybe something like my attempt at the code? */ Data want; Set have; If PM ^= ""
For i.&PM_items. to last.&PM_items. do;
&PM_items&i.
next i;
end;
Then output;
Run;
No macros needed.
Use COUNTW to determine the number of words.
Use SCAN() to separate into components.
Your logic is close:
n_words = countw(....);
Do I=1 to n_words;
Word = scan(....);
OUTPUT;
end;
