@v: Overload operator

This command begins the definition part.

@v is used to change the woven appearance of an operator. If one defines a new operator, for example by a statement such as

interface operator(.BETA.)

in FORTRAN-90, one should also use an @v in the definition part--for example,

@v .BETA. "\\beta" +
