DOCUMENT:Q108349 05-NOV-1999 [fortran] TITLE :BUG: Console I/O Problem; CR/LF Skipped After File Open PRODUCT :Microsoft Fortran Compiler PROD/VER::1.0,4.0 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Fortran Powerstation 32 for Windows NT, versions 1.0, 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== A console application that opens a file with a unit specifier of 5 may cause subsequent screen output to appear on the same line (without carriage return and linefeed characters). CAUSE ===== This problem seems to occur only when the application writes to the screen before opening unit 5. RESOLUTION ========== If unit number 5 must be used for an external file, OPEN that file before performing any WRITE statements to the screen. Running the program with MORE piping (for example, | MORE) to display output one screen at a time also alleviates the error. STATUS ====== Microsoft has confirmed this to be a problem in Microsoft FORTRAN PowerStation 32 for Windows NT, version 1.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available. MORE INFORMATION ================ The following sample program demonstrates the problem: Sample Code ----------- C Compile options required: none character*12 buffer do i=5, 7 write(buffer,'(i5,a)') i,'.dat' write(*,*) 'Filename is: ', buffer open(i,file=buffer) end do end Output ------ Filename is: 5.dat Filename is: 6.dat Filename is: 7.dat Additional query words: 1.00 4.00 handle ====================================================================== Keywords : Technology : kbAudDeveloper kbFortranSearch kbZNotKeyword2 kbFORTRANPower32100NT kbFORTRANPower32400NT Version : :1.0,4.0 ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
