BUG: Run-Time Error F6511 - Variable Name Not FoundLast reviewed: April 9, 1996Article ID: Q149477 |
The information in this article applies to:
SYMPTOMSWhen reading a file using namelist directed input, you may get the following error:
run-time error F6511 - variable name not found CAUSEThe file wasn't opened with the DELIM="{QUOTE|APOSTROPHE}" option in the Fortran OPEN statement used to open the file for writing. Microsoft Fortran PowerStation 4.0 requires the DELIM="{QUOTE|APOSTROPHE}" option if you are opening a file that is to be written with delimiters. However, when opening and using the file for a namelist directed I/O operation, the DELIM= option is not needed. Previous versions of Fortran did not include this option and character variables were always written with delimiting apostrophe's.
STATUSMicrosoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
