The control commands are executed in accordance with DIN 19239.
They comprise an operation part and an operand part. The control
command may also consist of the operation part only, e.g. open brackets
(, end of program (EP).
The operation part consists of up to 4 characters in the form of a com
mand mnemonic. It is divided into the operator (OPR) and the operator
attribute (OPA). The attribute defines the data format.
The operand part contains the necessary data to execute a command.
Operands can be written in symbolic or absolute notation. The oper
and part (depending on the operation part) is composed of one or two
operands. Each of these operands consists of an operand identifier
and a parameter. The parameter can be a bit, byte, or word address
(data format). In symbolic notation, the operand is identified with a pre
ceding −" and can consist of up to 8 characters (alphanumeric).
