used in the emulation of IBM 1401 instructions that were not directly compatible. In two-character address mode, the full address defined one character in the 4K block currently addressed by the relevant register. In three-character address mode, the first three bits of an operand address can designate one of six index registers that occupied the first 24 addressable memory locations. The other two possible bit patterns indicated no indexing (000), or indirect addressing (111). In four-character address mode, the whole installed memory (up to 512K on a Model 4200) was directly addressable, and in addition, the top five bits of each address can specify direct addressing, indirect addressing, or indexed addressing via two sets of 15 four-character registers; in a program running in protected mode both sets were the same, located in the first 60 locations of the memory area to which the program was relocated.

The
Easycoder assembler generated an object file as a binary card deck that can be punched to cards or written to magnetic tape instead. The object file began with a bootstrapping routine so that each program can be loaded into memory, from card reader or magnetic tape, using a boot command from the

An instruction consists of a one-character op-code, up to two operand addresses and an optional single character variant. Usually the op-code character would be word-marked, confirming the end of the previous instruction. An item-marked op-code would be handled differently from normal, and this was

In the Mod 2 operating system, the
Easycoder assembler and every compiler generated object modules on a "go file" on tape; these objects were then linked by means of the LINKLOAD program into one or more executable programs on a "job file", still on tape, which can either be run directly from the

The 200-series I/O instructions were a
Peripheral Data Transfer (PDT) and a Peripheral Control and Branch (PCB) that explicitly implemented asynchronous I/O. The PDT specified a device address, a buffer address and the transfer operation to be started, while the PCB specified a device address, a

Higher Series-200 computers (H1200, H1250, H2200 and H4200) were mainframes in their own right, capable of handling (with the Mod 2 operating system) up to two simultaneous job streams in addition to the "resident monitor" (i.e. the kernel). The top-end computer in the series (the H4200) had a

series machine. The H1800-II consisted of an H1800 mainframe equipped only with magnetic tape drives and an online adaptor (OLA) connection to a satellite H200 to simulate a card reader for reading low volumes of job control cards. The LINK program running on the H200 handled the OLA, copied

I/O instructions left punctuation bits unchanged, reading or writing only data (and parity) bits into memory, and terminating on any record mark encountered. A record mark could be placed at the end of an input buffer to prevent any buffer overflow, a problem that was to persist in many other

Sequence Mode (CSM) instruction exchanged the contents of the instruction counter and of a Change Sequence Register (two register of Control memory, slightly faster but much smaller than Main memory). This provided a simple switch between threads within a program, similar to the

branch address and set the operating mode or tested the status of the device (branching to the specified address if the specified condition was met, for instance if the device was busy doing I/O). Both used the format Op-code

While the H200 supported operation with just a console, card reader and punch like the IBM 1401, the generic Input-Output instructions also supported line printers, magnetic tape drives and disk drives.

A Change
Address Mode (CAM) instruction switched between 2-, 3- and 4-character address modes. The address mode specified the number of characters needed for each operand address in instructions.
