In the SAS log shown below, there is a note indicating that the variable Sale is uninitialized. What does that mean? Partial SAS Log 2 data January; 3 set sugi.salesdata; 4 if Month=1; 5 format Sale dollar11.2; 6 run; NOTE: Variable Sale is uninitialized. So, WARNING is green, ERROR is red, and I wanted my term -- NOTICE, for example -- to always show up in some other color, like orange or purple or something. This would be a cool thing to add to the capabilities of the SAS log, and I can't imagine that it would be any more difficult that the … I want to create something in SAS that works like an Excel lookup function. Basically, I set the values for macro variables var1, var2, and I want to find their index number according to the ref table. But I get the following messages in the data step.

Richard DeVenezia contributed the following trick: Uninitialized variables are powerful bugs since they can be exploited to leak arbitrary memory or to achieve arbitrary memory overwrite or to gain code execution, depending on the case. When exploiting a software which utilizes address space layout randomization , it is often required to know the base address of the software in memory. Once that is fixed (most of) your warnings should go away. You do still have some other bugs though, e.g. you use seconds as your input variable, but you then discard this and instead pass the uninitialised variable total to your function - you should probably just be using total as your input variable and get rid of seconds. If you want SAS to sum only the non-missing values, you can use the SUM function instead of the addition operator.

So no warnings, but if you are careful, you can avoid this mistake, because name “uninitialized” usually isn‘t what you want to see in your SAS log and you should check that everything really worked the way it was supposed to work. In SAS tips & tricks #9, we looked at what happens when SAS encounters an uninitialized variable within a DATA Step.Here we look at the possibly more serious scenario of what happens when SAS cannot find a reqruied variable within a PROC Step. You will usually notice that this has happened because the log will display the following message: NOTE: Variable num_1 is uninitialized.

In the SAS System, character values must be adjusted to the same length before they can be compared. When SAS THIS VARIABLE IS UNINITIALIZED Sometimes when one is coding a specified data set structure, some of the variables will be uninitialized. This results in the SAS Log message similar to: NOTE: Variable z is uninitialized.

6 at file, there may be a problem Needless to say both version of step1 produce the same dataset, in this case an empty dataset with variables 'value' and 'cat'. However: when running step1 in the way step1a is written, the SASlog will warn us that something is wrong: NOTE: Variable cat is uninitialized.

But I get the following messages in the data step. NOTE: Variable A is uninitialized.

The default behavior for the option is set to the value of NOTE to match the uninitialized variable message produced in all Samples & SAS Notes. Browse by Topic; Another solution is to make a static string to denote "uninitialized" value, and use Object.ReferenceEquals instead of == to check if it has changed. However, the bool variable approach expresses your intent a lot more explicitly. 2007-01-22 · Variables. You've already seen how a SAS data set is a matrix where each row is an observation and each column is a variable. SAS has two kinds of variables: numeric and character. SAS will attempt to identify the type of a variable by what you put in it.
