NAME
intro − introduction to file formats
DESCRIPTION
This section describes the formats of various include files, program output files, and system files.
The Section 4 DEC OSF/1 reference pages are made up of an OSF-supplied component and a Digital-supplied component. The title line of an OSF-supplied reference page carries an "OSF" label while the Digital-supplied reference pages are labeled "Digital".
If OSF-supplied code operates differently on Digital platforms or has Digital extensions, an Environment Notes section is added to the OSF-supplied reference page. All reference pages that have an Environment Notes section have an "Environment_Note_Added" label added to the title line.
When needed, technical corrections have been made to the OSF-supplied reference pages.
The suffixes used on some Digital-supplied reference pages are used only to allow reference pages with the same base name to exist on DEC OSF/1 systems. When used, suffixes are made up of one to four letters. See the man(1) reference page for more information on suffixes.
