ReplyDelete@5 age 2.;
ReplyDeleteSo B is the Ans:
Alfr14
Alic13
Barb13a (ar)(13)
Caro14
'B'
ReplyDeleteAnswer is
name age
"Alfred 14"
"Alice 13"
"Barbara 13"
"Carol 14"
Can anyone give an explanation why "C" is not right?
ReplyDeleteAnswer is B because @5 age 2. will not create space for itself but rather it will overwrite name $15, which is written first. So Alfred written by name variable will become Alfr14
ReplyDeleteI agree.
ReplyDeleteThere is no trim/cut and paste applied. BARBARA
ReplyDeletehas 7 letter on 5th & 6th sits the age still one more letter from BARBARA available goes at 7th,
Alfr14

C is the answer .
Below is the code I tried. Since Name and Age are already in a dataset, they are assumed to be formatted correctly. While put statement is used, since 5th position is mentioned for age, it will write over the name values
data team;
input name $ age;
datalines;
Alfred 14
Alice 13
Barbara 13
Carol 14
;
data students;
set team;
file 'File specification';
put name $15. @5 age 2.;
run;
When I tried your code the output is; SAS 9.3 answer seems to be 'D': Am I missing something?
DeleteName Age
Alfred 14

Basically whats missing the code above is File path and name in place of " FILE SPECIFICATION" ...we are writing a code to create a raw file , so specify a folder and a name for your file .. eg "C:\Users\someone\Desktop\xyz.txt" and after you run the code open that xyz.txt and see you will see exactly as given in Option B :) ... hope this helps
DeleteI have the same doubt with Anon, anyone can help with please?
DeleteThe answer is B. Code below- check the log when finished running for what would have been in the file.
