The diacritical expression places diacritical marks around multiple operands and describes two additional
diacritical marks. The
diacritical expression describes the same marks that the char expression describes, but it
can take multiple operands. In addition, the
diacritical expression describes two forms of diacritical mark not
described by the
char expression. The following table shows examples of diacritical expressions.
Note: The
diacritical expression is not backward compatible. When an earlier version (previous to 4.x) of
FrameMaker reads a MIF file saved in version 4 or later of FrameMaker, any equations that contain
diacritical
expressions are lost. You should edit any
MathFullForm statements that contain diacritical expressions before
opening the file in earlier versions of FrameMaker. For more information, see “Math statements” on page 250.
dummy
The dummy expression describes a dummy variable that you can use as a placeholder in equations. For example, in
the following equation, i is a dummy variable:
The
dummy expression has the same syntax as the char expression and can contain the same character symbols or
names.
Operator expressions
Operator expressions take at least one expression as an operand. There are no restrictions on the complexity of
operator expressions, and they are not restricted by any concepts of domain or typing.
Unary operators
Unary operators have one expression as an operand. Three of the unary operators—id, lparen, and rparen—have
multiple display formats. The following table contains an example of each unary operator (in all of its display
formats) with
char[x] as a sample operand.
Example MathFullForm statement
<MathFullForm `diacritical[4,0,0,0,0,char[x]]'>
<MathFullForm `diacritical[5,0,0,0,0,char[x]]'>
<MathFullForm
`diacritical[4,0,0,0,0,times[char[A],char[B]]]'>
Example MathFullForm statement
<MathFullForm `dummy[x]'>
