Last change on this file since 4643 was 4143, checked in by dcugnet, 3 years ago
  • Some variables are renamed or replaced by direct equivalents:
    • iso_indnum -> tracers(:)%iso_iName
    • niso_possibles -> niso
    • iqiso -> iqIsoPha ; index_trac -> itZonIso
    • ok_iso_verif -> isoCheck
    • ntraceurs_zone -> nzone ; ntraciso -> ntiso
    • qperemin -> min_qparent ; masseqmin -> min_qmass ; ratiomin -> min_ratio
  • Some renamed variables are only aliased with the older name (using USE <module>, ONLY: <oldName> => <newName>) in routines where they are repeated many times.
  • Few hard-coded indexes are now computed (examples: ilic, iso, ivap, irneb, iq_vap, iq_liq, iso_H2O, iso_HDO, iso_HTO, iso_O17, iso_O18).
  • The IF(isoCheck) test is now embedded in the check_isotopes_seq and check_isotopes_loc routines (lighter calling).
  • Property svn:keywords set to Id
