  SECTION_PARAMETERS
  	&BECKE88 {Logical}
  	activates the functional
  	This keyword cannot be repeated and it expects precisely one logical.
  	The lone keyword behaves as a switch to .TRUE.
  	Default value: .FALSE.

  SCALE_X
  	SCALE_X {Real}
  	scales the exchange part of the functional
  	This keyword cannot be repeated and it expects precisely one real.
  	Default value: 1.00000000E+000
