You can write the values of SAS automatic variables to the SAS log to help you analyze your program and data. Your code can test the values of SAS automatic variables to direct conditional execution of DATA step statements.
ReplyDeleteAutomatic variables are temporary and SAS does not store them in the data sets it creates. To save the value of an automatic variable, assign its value to a data set variable.
When to use:
Always review the SAS log to look for notes indicating that _ERROR_ was set to 1.
Set _ERROR_ to 1 in your code for errors you want flagged in the SAS log. FIRST.variable Indicates whether the data values being processed are from the first observation in a BY group where: variable is the BY-group variable to examine.
Answer is B and D..
ReplyDeleteThe value of _error_ is 0 or 1, not true or false (though they are logically equivalent). Answer is just D
DeleteAnswer D
ReplyDeleteD
ReplyDeleteAnswer is no B, because the value is 1 or 0
ReplyDeleteThe value is 1 or 0,it cannot be true or false.So D is the answer.
DeleteThe answer is A as on off means 0 or 1 and _error_ stores the value 1 when there is error or intitalizes it to 0 when no error is there.
ReplyDeleteanswer is D.
ReplyDeleteboth A and B are wrong because the question says the value of _ERROR_ is'ON' or "OFF' it refers to the word on and off not logical valu 0 and 1.
