USE Statement Needed for Fortran QuickWin Applications

A program using the Fortran QuickWin or Standard Graphics features must explicitly access the QuickWin graphics library routines with the statement USE IFQWIN.

Any program using the QuickWin features must include the statement USE IFQWIN to access the QuickWin graphics library. The IFQWIN.MOD module file contains subroutine and function declarations in INTERFACE statements, derived-type declarations, and symbolic constant declarations for each QuickWin routine.

USE statements must immediately follow the PROGRAM, SUBROUTINE or FUNCTION statement, and precede any IMPLICIT statement.

Depending on the type of routines used by your application, other USE statements that include other Fortran modules may be needed. The description of each Intel Fortran routine in the Language Reference indicates the module that needs to be included for external routines (such as USE IFCORE or USE IFPORT).
