Description of your issue or question

When I tried to build cam6_3_119 (with HEMCO tag: hemco-cesm1_2_0_hemco3_6_2_cesm) on Derecho with the nvhpc/23.1 compiler, the compilation failed with the error message below:

NVFORTRAN-S-0285-Source line too long (/glade/derecho/scratch/sunjian/CESM/components/cam/src/hemco/HEMCO/src/Core/hcoio_read_std_mod.F90: 65)
NVFORTRAN-S-0023-Syntax error - unbalanced parentheses (/glade/derecho/scratch/sunjian/CESM/components/cam/src/hemco/HEMCO/src/Core/hcoio_read_std_mod.F90: 65)

The culprit is that the GC_72_EDGE_SIGMA array in the hcoio_read_std_mod.F90 code (indicated by the line number above) is too long. The solution is to break the GC_72_EDGE_SIGMA array into multiple lines and use the continuation character.

Hi @sjsprecious, thanks for reporting it here. I will make a PR to fix this over here and once it is tagged I'll make a pull request at CAM.
