The IF statements in the following code example produce different results, based on whether the variables are in an array or not.

A workaround is to reverse the order of the variables in the IF statement, as shown here:

The Output tab shows the full example code, with the workaround, and the log output from each of the three IF statements.

The hot fix is for the SAS^® 9.4M7 (TS1M7) release.
