                     23: .SH DESCRIPTION
                     24: .I Perror
                     25: will write a message to fortran logical unit 0
                     26: appropriate to the last detected system error.
                     27: .I String
                     28: will be written preceding the standard error message.

                     30: .I Gerror
                     31: returns the system error message in character variable
                     32: .I string.
                     33: .I Gerror
                     34: may be called either as a subroutine or as a function.
                     35: .PP
                     36: .I Ierrno
                     37: will return the error number of the last detected system error.
                     38: This number is updated only when an error actually occurs.
                     39: Most routines and I/O statements that might generate such errors
                     40: return an error code after the call;
                     41: that value is a more reliable indicator of what caused the error condition.
