Application Variable Limit Check
Technical Alert TA20004 describes how an overflow in the numbering of temporary (internal un-
named) variables in a compiled application can cause corruption of I/O variables without warning. This
may occasionally affect large applications but is unlikely in small applications.
This document describes how to check for the temporary variable numbering overflow.
