9Rules:1. The END= specifier may appear only in a sequential access READstatement; note that the END= specifier must not appear in a WRITEstatement.2. If an IOSTAT= specifier is present, an end-of-file condition occurs, andno error condition occurs, the IOSTAT variable specified becomesdefined with a processor-dependent negative value.3. If the file is an external file, it is positioned after the end-of-file record.4. If an end-of-file condition occurs and no error condition occurs duringthe execution of the READ statement, the program branches to thelabel in the END= specifier. The label must be a branch target in thesame scoping unit as the READ statement.EOR= labellabelis the label of a branch target statement takenwhen an end-of-record condition occursRules:1. The program branches to the labeled statement specified by the EOR=specifier if an end of record is encountered for a nonadvancing READstatement. The label must be a branch target in the same scoping unitas the statement containing the EOR= specifier.2. The EOR= specifier may appear only in a READ statement with anADVANCE= specifier with a value of NO, that is, a nonadvancingREAD statement.3. If an end-of-record condition occurs and no error condition occursduring the execution of the READ statement:a. The file is positioned after the current record.b. The variable given in the IOSTAT= specifier, if present, becomesdefined with a processor-dependent negative value.c. If the connection has been made with the PAD= specifier of YES,the record is padded with blanks to satisfy the input item list andthe corresponding data edit descriptor that requires morecharacters than are provided in the record.364 Fortran 90 HandbookCopyright © 1992 J.
