What value does the variable idnum contain when the name of the employee is "Ruth"?

1. correct answer is A – 33 because the second line will be loaded into input buffer as there is a second input statement and no line holder indicator @ after the the 1st input statement (that normally should be if we want to read data correctly and avoid unexpected results).
   First input statement – input employee_name $ 1-4, second input statement- if employee_name=’Ruth’=>as there is implicit output at the end of the data step, the values of the pdv will be read into data set and for the 1st line where name =Ruth, the values of idnum will be those of the 2nd line from 10th to 11th position: 33
