Last change on this file since 5453 was 3981, checked in by Laurent Fairhead, 3 years ago

Adds a routine 'prt_alerte' to enable developpers to print out informative messages on the first pass through physics
and from the master process only. This can be used to remind oneself of potential problems or further enhancements.
Messages can be differentiated by a 'priority' code 0/1/2 (corresponding to GREEN/ORANGE/RED alerts)
By default, the messages are output in a file called ALERTES.txt but changing the unit number to 6 in the
print_control_mod.F90 file allows you to print out your messages to the screen.

To use you simply need to:

  • have this USE statement at the start of your routine:

USE print_control_mod, ONLY: prt_level, lunout, call_alert, prt_alerte

  • ensure that the modname variable is defined and contains the name of your routine
  • then you just need to add the following lines in your routine wherever you want to ouput your message (preferably not in a do loop)

message='your informative message'
IF (call_alert) CALL prt_alerte(message,modname,CODE)

where

  • message is the message to print out
  • modname is the routine name
  • CODE is an integer representing your priority code (0/1/2)

and you should get messages of the form

ALERTE ROUGE cva_driver! ym missing init, need to have a look by developpers
ALERTE VERTE orosetup_strato! ym correction en attendant mieux
