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
).
