SUMMARY
The Microsoft FORTRAN Optimizing Compiler "Language Reference" manual for versions 4.0, 4.01, and 4.1 and the Microsoft FORTRAN "Reference" manual for version 5.0 state that an application can open a named file with STATUS = 'SCRATCH.' These statements appear on page 253 for versions 4.x and page 206 for version 5.0.

These statements are incorrect and are contrary to ANSI FORTRAN specification (see page 12-19). The FORTRAN compiler generates the following run-time error when an application specifies STATUS = 'SCRATCH' for a named file:

F6301 : SCRATCH illegal for named file

NOTE: This feature is supported in FORTRAN PowerStation.



MORE INFORMATION
The following code example demonstrates this run-time error:

Sample Code #1
C Compile options needed: None

OPEN(6, FILE = 'JUNK', STATUS = 'SCRATCH') END To implement a named scratch file, open the file without a STATUS specification and close the file with STATUS = 'DELETE.' The following code example demonstrates this technique.

Sample Code #2
C Compile options needed: None

OPEN(1, 'FILE = TEST.DAT') CLOSE(1, STATUS = 'DELETE') END
