The diagnostics for the options of OPEN, INQUIRE, WRITE, READ and potentially
also CLOSE could be improved. Currently, gfortran only prints "SYNTAX ERROR"
for:
inquire(99, pad=3) ! wrong, need CHARACTER variable not INTEGER literal
inquire(99, pad='aaa') ! wrong, need variable
end
NAG f95 has a better message:
Error: aa.f90, line 1: Expected a CHARACTER item for i/o keyword PAD
Error: aa.f90, line 2: Item for i/o keyword PAD is not a variable
As had ifort:
fortcom: Error: aa.f90, line 1: A scalar default-character variable is required
in this context. [3]
inquire(99, pad=3) ! wrong, need CHARACTER not INTEGER
----------------^
fortcom: Error: aa.f90, line 2: A scalar default-character variable is required
in this context. ['aaa']
inquire(99, pad='aaa') ! wrong, need Variable
----------------^
