SAS re-initialized

[Guru_MG]

The dataset orion.counsellor contains the following variables: Counsel_ID, DateOfBirth, Yrs_Exp, Salary.
Given the following code:
Data counsel_new;
Set orion.counsellor;
Study = Yrs_Exp + 3;
Bonus = Salary * 1.05;
Run;
Which of the following variables will be re-initialized at the start of each iteration of DATA Step?
(a) Yrs_Exp
(b) Counsel_ID
(c) Bonus
(d) DateOfBirth

What is your answer, and why?

Hi @Guru_MG,

Writing and testing small programs is very useful when learning SAS. So, why not observe what happens in practice (maxim 4)?

Spoiler

/* Create test data (if orion.counsellor does not yet exist) */

libname orion (work);

data orion.counsellor;
input Counsel_ID $ DateOfBirth Yrs_Exp Salary;
cards;
0 1 2 3
4 5 6 7
;

/* Run the DATA step in question with diagnostic PUT statements added */

data counsel_new;
put 'Start of iteration ' _n_ ': ' _all_;
set orion.counsellor;
Study = Yrs_Exp + 3;
Bonus = Salary * 1.05;
put 'End of iteration   ' _n_ ': ' _all_;
run;
