      IMPLICIT REAL (R)

      IMPLICIT DOUBLE PRECISION (D)

      IMPLICIT COMPLEX (C)

      IMPLICIT DOUBLE COMPLEX (Z)

      IMPLICIT INTEGER (I-N)

The base name of the subroutine identifies the operation performed:

COSQB	Backward cosine quarter-wave transform (synthesis)
COSQF	Cosine quarter-wave transform
COSQI	Initialize cosine quarter-wave transform or synthesis
COST	Cosine even-wave transform
COSTI	Initialize cosine even-wave transform
EZFFTB	Backward EZ transform (synthesis)
EZFFTF	EZ transform
EZFFTI	Initialize EZ transform
FFTB	Backward transform (synthesis)
FFTF	Forward transform
FFTI	Initialize before applying a transform or synthesis
SINQB	Backward sine quarter-wave transform (synthesis)
SINQF	Sine quarter-wave transform
SINQI	Initialize sine quarter-wave transform or synthesis
SINT	Sine odd-wave transform
SINTI	Initialize sine odd-wave transform

These subroutine names may have a one or two-letter prefix that identifies the type of operands processed:

No prefix:	Operands are real.
R	Operands are real.
D	Operands are double precision.
C	Operands are complex.
Z	Operands are double complex.
VR	Subroutine operates on multiple vectors supplied simultaneously; operands are real.
VD	Subroutine operates on multiple vectors supplied simultaneously; operands are double precision.
