Consider the following program:
parabrisas:~/test% cat C578.f
subroutine s( )
logical frstme
save frstme
save
continue
end
Under constraint C578 of the f95 standard this is illegal, since a global save
is not permitted in the same scoping unit as any other explicit use of the
save attribute or save statement. gfortran correctly recognises this and
diagnoses an error.
However, this constraint did not exist in F77 (I am unsure about F90).
Therefore, the above is a perfectly legal F77 program (and, indeed g77
compiles it without complaint).
