File No. 1401/1460-22 Form C24-3319-0 1650351 Systems Reference Library Autocoder (on Tape) Language Specifications and Operating Procedures IBM 1401 and 1460 Program 1401-AU-037 This reference publication contains the language specifications and operating procedures for the Autocoder (on Tape) programming system. The IBM 1401 Autocoder processor program produces machine-language object programs for IBM 1401 and IBM 1460 from source programs written in the symbolic language of Autocoder. The language specifications are divided into two sections. The first section contains the specifications of the symbolic language (mnemonics, labels, address types, and control operations) and the rules for writing the source program. The second section describes macro operations and macro instructions'. The operating instructions supplement the language specifications section of this publication. Described are the procedures to be performed by the operator when assembling an Autocoder program on an IBM 1401 or 1460 tape system. The phases of the Autocoder processor are explained and system halts and restarts are given.
