OS/2 V2.0 provides a number of standard, CUA-conforming dialogs which may be used by applications to perform common operations such as file handling and font selection. The provision of these dialogs within the operating system avoids the need for applications to individually develop dialog boxes and procedures for these functions. This delivers a high degree of consistency between similar operations in different applications.
Both forms of the standard file dialog are accessed by an application using the WinFileDlg() function. This function is explained further in OS/2 Version 2.0 - Volume 4: Application Development.
