Fortran 2008 coarray emulations of Fortran 2018 intrinsic collective subroutines and Fortran 2003 emulation of Fortran 2008 intrinsic procedures (e.g, findloc)
parallel one-to-all communication of the value of first argument
parallel computation of the sum of the first argument
result is the last occurrence of a value in an array or zero if not found
