| can be any number of statements P For the controlling expression of a DO loop is a statement Is a continue statement in Fortran a DWARF statement P Each function whether user coded or generated by the is a statement This is so one can step | over (in a debugger) the final user-coded statement(exclusive of the return statement if any) in a function wile not leaving the function scope..P.H 2"Finding The First User Code in a Function".nf Consider |
