Visual Fortran includes functions and subroutines that ease porting of code from a different platform to a PC, or allow you to write code on a PC that is compatible with other platforms. Frequently used functions are included in a module called DFPORT.
This chapter describes how to use the portability module, and describes routines available in the following categories:
When writing new code, use Fortran 95/90 contains intrinsic procedures whenever possible (for portability and performance reasons). Fortran 95/90 contains intrinsic procedures for many of the portability functions. The portability routines are extensions to the Fortran 95 standard.
