Caveat:
|
|
|
|
|
|
|
|
Wrong: FN=* { X=$FN } there is no variable called FN
|
|
|
|
Right: FN=* { X=$$ } yields the Fn field selected by FN
|
|
|
|
|
|
|
|
Wrong: VAL=(#R) { R=$VAL } yields literal value
|
|
|
|
Wrong: VAL=(#R) { R=$$ } yields literal value
|
|
|
|
Right: VAL=(#R) { R=$1 } yield canonicalized value
