WebFortran 90 supports two forms of source code; the old Fortran 77 source code form (now calledﬁxed form), and the new free form. Using free source form, columns are no longer reserved and so Fortran statements can now appear anywher e on a source line. The source line may contain up to 132 characters. WebThe open command is used to open files - that is, it makes files available so that Fortran can read or write to them. The simplest form of the command is open (unit = number, file = " name ") . In place of number you insert a positive integer (but not 6) to be used to refer to the file, and instead of name you insert the name of the file.
