B
Please explain
‘Chem2’ is not same as ‘chem2’
‘Chem2’ is a string, therefore it’s case sensitive. ‘chem2’ is not ‘Chem2’.
The data is case sensitive though the variable names and data set names are not.. Chem2 is not same as chem2
cause ‘chem2’ ^= ‘Chem2’
but there’s an mistake: libnamesasdata doesn’t work
String variables are case-sensitive. ‘Chem2’ is different from ‘chem2’ therefore the else statement is triggered.
The data set name used is ‘set’ which is a SAS keyword. Is it not an error?
