An uninitialized variable automatically take the value in the "accumulator" (integral: eax, rax; floating point/simd: xmm0, ymm0, zmm0, etc.) and not load it from random access memory (or cache) unless it is volatile. You can initialize the variable by assigning a value to it, given the non-lvalue does not use an uninitialized variable.
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: If a variable name is specified only in the RETAIN statement and you do not specify an initial value, the variable is not written to the data set, and a note stating that the variable is uninitialized is written to the SAS log.
