Enter the control command to be called

Applications can be controlled by calling object methods, setting
object attributes, or retrieving object attributes.
The exact sequence and syntax of control calls can be found in the
documentation of the application to be controlled.
A distinction is made between 3 control commands:
Method call
Syntax: <(><<)>method name> <(><<)>variable name>
or <(><<)>method name> = <(><<)>variable name>
When a method is called, several variables can be passed which must be
separated by a comma
Getting an object attribute (not for Apple)
Syntax: <(><<)>variable name> = <(><<)>attribute>
Setting an object attribute (not for Apple)
Syntax: <(><<)>attribute> = <(><<)>variable name>
It is possible to pass variables in the control calls. The following
variables are defined and are evaluated:
@AID Storage system ID
@DPA File name on the frontend
@DTI Document class
@DID Document ID
@SPA Path on the application server
@STA Window ID
@ATI Number of retrieved files
@ADA Names of retrieved files
@UID User name
@LAN Logon language
@ETX Error text
@DPO Document path
@PAG Page number
@FPA Frontend path
@EID Error number/Returncode
@STA Status of stored document
@ATI Storage time of stored document
@ADA Storage date of stored document
@LSI,,,,Logical system (unique system identification for the SAP
System)
