61 |
|
|
! Original : 95-10-01 |
62 |
|
|
! David Dent:97-06-02 parameters KFRSTLAT etc added |
63 |
|
|
! JF. Estrade:97-11-13 Adaptation to ALADIN case |
64 |
|
|
! J.Boutahar: 98-07-06 phasing with CY19 |
65 |
|
|
! Modified 98-08-10 by K. YESSAD: removal of LRPOLE option + cleanings |
66 |
|
|
! (correct computation of extrapolar latitudes for KPROCL). |
67 |
|
|
! Modified 98-12-07 by K. YESSAD and C. FISCHER: cleaning. |
68 |
|
|
! - merge old sumplat.F and suemplat.F |
69 |
|
|
! - gather 'lelam' code and 'not lelam' code. |
70 |
|
|
! - clean (useless duplication of variables, non doctor features). |
71 |
|
|
! - remodularise according to lelam/not lelam |
72 |
|
|
! -> lelam features in new routine suemplatb.F, |
73 |
|
|
! not lelam features in new routine sumplatb.F |
