SYMPTOMS
If one or more blanks precede a NAMELIST comma separator, it will generate the following run-time error at the input line:

run-time error F6511:

input_operation(filename.***) -variable name not found

The error can also occur if there are repeat factors in a comma separated NAMELIST or if there are spaces after repeat factors in a NAMELIST which are not separated by commas.



RESOLUTION
The comma value separator must immediately follow the variable name. Removing blank(s) between the NAMELIST variable and the following comma separator will resolve this problem.



STATUS
Microsoft has confirmed this to be a problem in Microsoft FORTRAN PowerStation 32 for Windows NT, version 1.0. This problem was corrected in FORTRAN PowerStation version 4.0.



MORE INFORMATION
A NAMELIST value separator can be a single comma or one or more blanks. Tabs are valid as white-space separators. Blanks are not allowed between a NAMELIST variable and the comma following.

Sample Code
The following sample program and NAMELIST data set produces run-time error F6511 at the READ statement: NAMELIST /SECT1/STX, STY OPEN (15, FILE='NM.DAT', STATUS='OLD') READ (15, SECT1) STOP END

NM.DAT Data Set 1
&SECT1 STX= 0.0000, STY=10.0000 / The following data set does not generate the error:

NM.DAT Data Set 2
&SECT1 STX=0.0000, STY=10.0000 /
