ncfile_enter_groups Subroutine

public subroutine ncfile_enter_groups(sf, varname_in, grpid, varname, exists)

if variable name contains "/", these are interpreted as groups/subgroups. split the varname at first occurence of "/" to get the first group name on the file level. Then get the group id. repeat until no "/" is found anymore. output the final groupid and the variable name without the group names.

Type Bound

t_ncfile
