Subject: SAS Question
I'm using SAS V6.8 in the mainframe platform. My input flat file contains a field defined as packed-decimal. When I tried to compare it with literal zero, it does not give me the correct evaluation even if the field actually contains a zero value packed-decimal.
INPUT @01 varnum PD8.3; /* varnum has X'000000000000000F' */
IF (varnum NE 0.00) or (varnum NE .)
THEN varvalid = 'N';
ELSE varvalid = 'Y';
I got varlid equal to 'N'. Why?
I was able to go around it by changing the condition to :
IF ((varnum * 1) NE 0)
Why do I have to perform a numeric operation before it arives to the correct answer?
Thanks for your help in advance.
