Script execution instruction

Script execution instruction
	Script execution

Description

The script execution instruction is used to execute a specified script of an RSE (type, factory or service).

Input argument values are transferred to the script through input argument assignments and output argument values are transferred from the script through output argument assignments.

See also the section called “Script execution tail” for information about specific error handling.
