By default ifort will determine the source format based the file extension:

    Files with an extension of .f90, .F90, or .i90 are free-format source files.

    Files with an extension of .f, .for, .FOR, .ftn, .FTN, .fpp, .FPP, or .i are fixed-format files.

 

You can also use compiler option "-free" or "-fixed" to specify the file format.

Another possible reason for the error is the length of statement field in a fixed format source file. By default the length is 72. It can be changed by option "-extend-source <size>" where the "<size>" can be 72, 80 or 132.

Thanks,
