Parsing error with names starting as: "DO_" (Fortran_2003)

[NicolasAnquetil]

Parsing error on file https://gitlab.inria.fr/croco-ocean/croco/-/blob/master/PISCES/p4zagg.F90

fortran-src: ./PISCES/p4zagg.F90, 76:12: ./PISCES/p4zagg.F90: parsing failed. 
Last parsed token: TUnderscore (76:11)-(76:11).
CallStack (from HasCallStack):
  error, called at app/Main.hs:117:36 in main:Main

(fortran-src version: 0.16.7)

The line in question is : DO_3D( 0, 0, 0, 0, 1, jpkm1 )
and this might be due to the name starting with "DO_" (or just "DO" ?)
