16!     Explicit arguments - input :
17!     --------------------
18!                          KDGL       -last  latitude
19!                          KPROCA     -number of processors in A direction
20!                          KMYSETA    -process number in A direction
21
22!     Explicit arguments - output:
23!     --------------------
24
25!                          KULTPP     -number of latitudes in process
26!                                      (in Fourier space)
27!                          KPROCL     -process responsible for latitude
28!                                      (in Fourier space)
29!                          KPTRLS     -pointer to first global latitude
30!                                      of process (in Fourier space)

51!     Modifications.
52!     --------------
53!        Original : 95-10-01
54!        David Dent:97-06-02 parameters KFRSTLAT etc added
55!        JF. Estrade:97-11-13 Adaptation to ALADIN case
56!        J.Boutahar: 98-07-06  phasing with CY19
57!        Modified 98-08-10 by K. YESSAD: removal of LRPOLE option + cleanings
58!         (correct computation of extrapolar latitudes for KPROCL).
59!        Modified 98-12-07 by K. YESSAD and C. FISCHER: cleaning.
60!         - merge old sumplat.F and suemplat.F
61!         - gather 'lelam' code and 'not lelam' code.
62!         - clean (useless duplication of variables, non doctor features).
63!         - remodularise according to lelam/not lelam
64!           -> lelam features in new routine suemplatb.F,
65!              not lelam features in new routine sumplatb.F
