BUG: WRITE Fails with Preconnected Unit=5 in Console Program

• Microsoft FORTRAN PowerStation 32 for Windows NT, version 1.0
• Microsoft FORTRAN PowerStation for Windows 95 and Windows NT, version 4.0

SYMPTOMS

In a console application, when you open and close a file with the preconnected unit=5 and perform a WRITE of a character string to the display, the written string is not terminated with a carriage return or with linefeed characters.

RESOLUTION

Use any file unit number other than 5 when performing file I/O.
