                     18: .I Perror
                     19: will write a message to fortran logical unit 0
                     20: appropriate to the last detected system error.
                     21: .I String
                     22: will be written preceding the standard error message.
                     23: .PP
                     24: .I Gerror
                     25: returns the system error message in character variable
                     26: .I string.
                     27: .I Gerror
                     28: may be called either as a subroutine or as a function.
                     29: .PP
                     30: .I Ierrno
                     31: will return the error number of the last detected system error.
                     32: This number is updated only when an error actually occurs.
                     33: Most routines and I/O statements that might generate such errors
                     34: return an error code after the call;
                     35: that value is a more reliable indicator of what caused the error condition.
