To select the Intel
Double-click the target you want to change in the Target group under the Groups & Files list.
In the Target Info window, click Rules.
To add a new rule, click the + button at the bottom, left-hand corner of the Target Info window. From the new Rule section:
under Process, choose Fortran source files
under Using, choose using Intel® Fortran Compiler

If you select a tool that does not support the source file type, that source will be processed by a later rule that specifies that type.
Once you have added a Fortran source file and a Target Info Rule, you can view and adjust the Intel compiler option settings. For more information, see Setting Compiler Options.
