Advice on Replacement Calls for Withdrawn/Superseded Routines
The following list gives the names of routines that are suitable replacements for routines that have either been withdrawn or superseded since Mark 18.
The list indicates the minimum change necessary, but many of the replacement routines have additional flexibility and you may wish to take advantage of new features. It is strongly recommended that you consult the routine documents.

E01TGF for interpolation of scattered data in three dimensions.
The interpolant generated by the two routines will not be identical, but similar results may be obtained by using the same values of

NQ. Details of the interpolant are passed to the evaluator through the arrays
IQ and
RQ rather than FNODES and RNW.

Withdrawn at Mark 24.
Replaced by
G05YLF.
Old: CALL G05YGF(IDIM,IREF,ISKIP,IFAIL)
New: GENID = 3
CALL G05YLF(GENID,IDIM,IREF,LIREF,ISKIP,IFAIL)
G05YHF
Withdrawn at Mark 24.
Replaced by
G05YMF.
Old: CALL G05YHF(N,QUASI,IREF,IFAIL)
New: CALL G05YMF(N,RCORD,QUAS,LDQUAS,IREF,IFAIL)
G05ZAF
Withdrawn at Mark 22.
There is no replacement for this routine.
G05ZAF was used to select the underlying generator for the old style random number generation routines. These routines are no longer available and hence no direct replacement routine for
G05ZAF is required. See
G05KFF and
G05KGF for details on how to select the underlying generator for the newer style routines.
G10 – Smoothing in Statistics
G10BAF
Scheduled for withdrawal at Mark 27.
Replaced by
G10BBF.
Old: CALL G10BAF(N,X,WINDOW,SLO,SHI,NS,SMOOTH,T,USEFFT,FFT,IFAIL)
New: ALLOCATE(RCOMM,NS+20)
CALL G10BBF(N,X,1,WINDOW,SLO,SHI,NS,SMOOTH,T,USEFFT,RCOMM,IFAIL)
! the next step is only required if the information in FFT
! was being used outside another call to G10BAF
FFT(1:NS) = RCOMM(21:NS+20)
G13 – Time Series Analysis
G13DCF
Withdrawn at Mark 24.
Replaced by
G13DDF.
Old: CALL G13DCF(K,N,IP,IQ,MEAN,PAR,NPAR,QQ,KMAX,W,PARHLD,EXACT,IPRINT, &
CGETOL,MAXCAL,ISHOW,NITER,RLOGL,V,G,CM,LDCM,WORK,LWORK, &

New: CALL G13DDF(K,N,IP,IQ,MEAN,PAR,NPAR,QQ,KMAX,W,PARHLD,EXACT,IPRINT, &
CGETOL,MAXCAL,ISHOW,NITER,RLOGL,V,G,CM,LDCM,IFAIL)
The workspace arguments WORK, LWORK, IW and LIW are no longer required in the call to
G13DDF.
