/[no]free

Syntax:

/free, /nofree,/4Yf, or /4Nf

The /free or /4Yf option specifies that the source file should be interpreted as being in free source format. Equivalent options are as follows:

• The /nofixed, /free, and /4Yf options are equivalent and request free-source form.
• The /fixed, /nofree, and /4Nf options are equivalent and request fixed-source form.

In the visual development environment, specify the Source Form in the Fortran Language Compiler Option Category.

If you omit /[no]free, /[no]fixed, /4Nf, and /4Yf, the compiler assumes:

• Files with an extension of .f90, .F90, or .i90 are free-format source files.
• Files with an extension of .f, .for, .FOR, or .i are fixed-format files.
