Cause
There are certain words that are restricted for use. You can find these words in the AVEVA Plant Scada manual. Reserved Words may be different version to version. Some reserved words like "Array" or "While" may result in a compiler warning. Other reserved word errors may end up causing functions to fail.
Using reserved words should be avoided as much as possible.
