Restrictions on auto-generated expressions

When the software auto-generates expressions, it replaces blank spaces and some characters as follows:

Unsupported character	Unsupported character description	Replacement	Replacement character description
	Blank space	_	Underscore
.	Period	_	Underscore
(	Parenthesis	_	Underscore
)	Parenthesis	None. The character is dropped.
{	Brace	None. The character produces an error.
}	Brace	None. The character produces an error.
&	Ampersand	None. The character produces an error.
–	Dash	None. The character produces an error.

All expressions must have unique names. Because the software auto-generates expressions for certain variables, duplicate expression names occur if you open a part that contains an expression whose name is identical to one of the auto-generated expression names. To prevent this from occurring, use the Variable Prefix, Rename Existing Expressions, and Rename Prefix customer defaults.

• If the Rename Existing Expressions customer default is enabled, the software pre-pends the text string defined by the Rename Prefix customer default to any existing expression names that are the same as an auto-generated expression name. The software does not use the Variable Prefix customer default when Rename Existing Expressions is enabled.

• If the Rename Existing Expressions customer default is disabled, the software pre-pends the text string defined by the Variable Prefix customer default to any auto-generated expression names that are the same as an existing expression name. The software does not use the Rename Prefix customer default when Rename Existing Expressions is disabled.
