Editing IBM PCjr BASIC Reference (June 1983)

The '''IBM PCjr BASIC''' reference (Hardware Reference Library), '''First Edition, June 1983''', '''IBM part number 1507784''', written '''by Microsoft Corp.''' for IBM. 682 pages.

Its preface is worth quoting because it settles a common confusion: "This book is a reference for '''both Cartridge and Cassette versions''' of BASIC for the PCjr. Throughout this book, the term BASIC refers to both versions". A separate ''BASIC Tutorial'' was shipped with the machine to teach programming; this book assumes you already can.

== What it contains ==

The full PCjr BASIC language reference &mdash; commands, statements, functions and variables, with syntax, remarks and examples &mdash; covering the PCjr's extensions over PC BASIC, including its sound and graphics capabilities.

== What it does not contain ==

'''No text layer''' &mdash; an image-only scan of 682 pages.

No hardware content: no voltages, no pinouts, no FRU numbers, no schematics, no component values. For PCjr hardware see [[IBM PCjr Technical Reference]].

== What it settles ==

It confirms the two-version structure of PCjr BASIC &mdash; '''Cassette BASIC in ROM and Cartridge BASIC on a plug-in cartridge''' &mdash; and documents them as one language, which is the correct reading when a program fails on one and not the other.
