Intel® Fortran Compiler 18.0 Developer Guide and Reference
Some compiler directives and compiler options have the same effect, as shown in the table below. However, compiler directives can be turned on and off throughout a program, while compiler options remain in effect for the whole compilation unless overridden by a compiler directive.
The following table shows compiler directives and equivalent command-line compiler options:
