FUNCTIONS
6.1.8 Arithmetic processing function (Operation action)
The arithmetic processing function performs operations for tag component values.
In this function, up to 20 dyadic operations can be processed per operation action.
By storing an operation result in the temporary variable area, complicated operations are
also executable.
For the arithmetic processing function setting, refer to the following:
Section 7.11.4 Setting items in Operation action
6.1.9 Program execution function
The program execution function is used for executing programs in the application server
computer before execution of the first action and after execution of the last one in a job.
For the program execution function setting, refer to the following:
Section 7.10.3 Setting items in Program execution
Programs that can be executed from [Command line] are applicable.
Since program execution is set on the server computer as described below, more
sophisticated data linkage can be realized.
(1) Before executing the first action of the job
By executing programs before the first action of the job, data required for the job can
be produced on the database in advance.
(2) After executing the last action of the job
By executing programs after the last action of the job, data written to the database by
the job can be utilized for programs on the server computer.

Executed in order
The result can be
assigned to a tag
component or
temporary variable.
Four operations and
remainder can be specified
by corresponding operators.
An operand is selectable from
tag component, constant and
temporary variable.
Up to 20 dyadic operations
can be performed for one
operation action.
