Replace an Element

The commands

REPLACE,SELECTED,BY=new-name;
REPLACE,ELEMENT=place,BY=new-name;

replace one or more element(s) in the sequence. Two cases are possible:

SELECTED

All currently selected elements are replaced by an occurrence of the element new-name.

ELEMENT=old-name

The (unique) element at place is replaced by new-name. It is an error if old-name is not unique.

Example:

REPLACE,ELEMENT=QF15,BY=QF17; // replace one element
