Section I. INTRODUCTION
General Information
The HP 13256A is made up of a 9-track magnetic tape containing HP 2645A terminal source code,
an HP 8080 Cross Assembler program, and various data files and utility programs. The assembler
is designed to run on an HP RTE-II or RTE-III system. This allows you to use the RTE system file
manager, editor and other library programs available on the RTE system. The system must contain
an HP 79708 magnetic tape drive. The remaining descriptions in this manual assume that you are
familiar with the HP RTE system, RTE file manager, and the RTE editor.
The HP 13256A tape files are described in table 1.

RTE System Software
File Manager
The RTE File Manager can be used to store, list, and dump source programs. However, it cannot
be used to store or dump object programs. Object programs require special formatting for output.
The utility programs described later in this manual are used to output the object code. If you have
special output requirements, you can develop a simple application program based on the existing
utilities.
Editor
The RTE Interactive Editor can be used to create and edit source programs. Refer to the RTE
documentation for additional information on the editor. Note that the semicolon (" ; ") normally used
by the editor as a tab character is also used by the assembler as a delimiter in source programs.
Before using the editor it is necessary to instruct the editor to use the colon (": ") as the new tab
character. This is done by typing liT: 8 : 22 ") after the editor is called and before the first edit
operation is begun.
