Error message

 Syntax error at line 1 while checking:
   x**2
    ^
 Expression expected.

Cause

The expression entered (usually into the Definition attribute, but possibly into the Check attribute or domain expression) is not a valid Analytica expression. In the above example, Analytica has no ** operator, hence the ** is not recognized. Syntax errors might be caused from missing operators (e.g., 4 x instead of 4*x), extra closing parentheses, unrecognized symbols, etc.

Remedy

Fix the specified syntax error.

-The expression entered (usually into the Definition attribute, but possibly into the [Check attribute] or [Domain Attribute|domain expression]) is not a valid Analytica expression.  In the above example, Analytica has no <code>**</code> operator, hence the <code>**</code> is not recognized.  Syntax errors might be caused from missing operators (e.g., <code>4 x</code> instead of <code>4*x</code>), extra closing parens, unrecognized symbols, etc.
