Write (nout,*) 'G05TCF Example Program Results'
Write (nout,*)

!     Skip heading in data file

!     Read in the base generator information and seed

!     Initial call to initialiser to get size of STATE array
lstate = 0
Allocate (state(lstate))
ifail = 0
Call g05kff(genid,subid,seed,lseed,state,lstate,ifail)

!     Reallocate STATE
Deallocate (state)
Allocate (state(lstate))

!     Initialize the generator to a repeatable sequence
ifail = 0
Call g05kff(genid,subid,seed,lseed,state,lstate,ifail)

!     Read in the distribution parameters

!     Use suggested value for LR
If (p<x02amf()) Then
!       P is too close to 0.0 to calculate LR, so
!       set to MAXLR, which means we will use MODE = 3
lr = maxlr
Else
lr = int(8.0E0_nag_wp+4.2E1_nag_wp/p)
End If

!     If R is a reasonable size use MODE = 2
!     else do not reference R and use MODE = 3
If (lr<maxlr) Then
mode = 2
Else
mode = 3
lr = 0
End If

Allocate (x(n),r(lr))

!     Generate the variates
ifail = 0
Call g05tcf(mode,n,p,r,lr,state,x,ifail)

!     Display the variates
