Hi, I am trying to compile my own Fortran90 code with a (large) number of routines written in Fortran77. I get errors that indicate that the compiler is case-sensitive for variables and functions, while the old F77 codes are somewhat sloppy in that respect. Is there a flag to make sure that gfortran does not distinguish upper and lower case? Apologies if this is a trivial question. Many thanks, Adam
