INTRODUCTION
This manual pertains to programming DMC 2 motion controller products and
contains a language reference that explains instructions, extended registers,
language syntax and compiler functions.
Typefaces used in this manual:
Mono spaced This typeface represents text as it appears on the screen (in
ECT) or in a program and is also used to indicate items the
programmer may type.
Italics Italics are used to emphasize certain words, such as new
terms.

GENERAL
Program A Program is comprised of a collection of Program
Statements.
i
Program
Statement
The DMC 2 product family allows a Program to be stored in
volatile memory,(RAM) or in nonvolatile memory
(FLASHPROM). The program can also be a file that is
stored on a computer when the development environment
(ECT) is used.
A program statement is one line of text that contains a
mnemonic for an instruction. Each instruction has its own
syntax. (The compiler checks for the correct syntax. The
controller has a built in one-line compiler.)
Line The sequential number where a program instruction is stored.
(1-8191)
Mnemonic A mnemonic is a text synonym for an instruction. The DMC 2
Mnemonic
Operator
family of products directly interprets Mnemonics.
Note: Occasionally, instructions refer to the Mnemonic for the
instruction.
An operator used together with a Mnemonic to define the
Instruction.
Argument One or several arguments are used with a Mnemonic to define
the Instruction.
Expression
Operator
Used with a Mnemonic and Argument(s) to define an action
that should take place during execution of the Instruction.
Routine A part of a program, usually designated to perform a certain
function, is called a Routine.
A Program is typically made up of many Routines.
Parameter stack Part of the memory organized as a FILO for parameter
storage.
[Mnemonic] Designates an optional Mnemonic.
Example: The Let Mnemonic can usually be omitted.
Syntax There are different ways to combine a Mnemonic together with
arguments and an operator. This will yield different
