Instruction list (IL) is one of the 5 languages supported by the initial versions of IEC 61131-3 standard, and subsequently deprecated in the third edition. [1] It is designed for programmable logic controllers (PLCs). It is a low level language and resembles assembly. All of the languages share IEC61131 Common Elements. The variables and ...
SCPI was defined as an additional layer on top of the IEEE 488.2-1987 specification "Standard Codes, Formats, Protocols, and Common Commands". [4] The standard specifies a common syntax, command structure, and data formats, to be used with all instruments.
User manuals and user guides for most non-trivial PC and browser software applications are book-like documents with contents similar to the above list. They may be distributed either in print or electronically. Some documents have a more fluid structure with many internal links.

[2] Part 3 of IEC 61131 deals with basic software architecture and programming languages of the control program within PLC. It defines three graphical and two textual programming language standards: Ladder diagram (LD), graphical
The instructions are mostly compatible with the mid-range 14-bit instruction set, but limited to a 6-bit register address (16 special-purpose registers and 48 bytes of RAM) and a 10-bit (1024 word) program space.
BASIC-8, is a BASIC programming language for the Digital Equipment (DEC) PDP-8 series minicomputers.It was the first BASIC dialect released by the company, and its success led DEC to produce new BASICs for its future machines, notably BASIC-PLUS for the PDP-11 series.
Byte 1 specifies two 4-bit length fields or one 8-bit length field; bytes 2-3 and 4-5 each specify a base and displacement. The encoding of the length fields is length-1. Instructions must be on a two-byte boundary in memory; hence the low-order bit of the instruction address is always 0.
