The ST parser detected a syntactical error in an ST code construct: a statement is not complete because an expression is missing.
This could be, for example, the control expression (to be evaluated) in an iteration statement (FOR loop) or the right part of an assignment statement.
The error can also be contained in a selection statement (IF or CASE).
The code position where the element is expected is underlined red in the code editor. Possibly, the error causes subsequent messages.
The Edit Wizard prevents entering syntactical errors. Using the Edit Wizard, syntax templates prepared with place holders can be inserted.
Refer to the topic "ST Code Elements" for information on the ST syntax.
