Forces complete elaboration of each subtree wherever it occurs in the listing.
Normally, a routine only has its subtree listed on its first occurrence and subsequent occurrences refer back to the first. This option may be used to prevent the listing line width being exceeded in deep call trees. Produces an index which lists, for each program-unit, the line of the call tree on which its subtree begins. If this option is set then all attribute files, see below, generated by this script from Fortran 77 source files are kept. These are given the file extension .atr and are created, or replace existing files, in the current working directory.
