Within a Batch Processing script, values are assigned to predefined variables by the equal sign. In the following example the value “2” is assigned to the variable “LogLevel”:
LogLevel = 2 # This is a remark
In the second row in the example above a comment is given starting with the hash symbol “#”. Such rows are ignored. It is impossible to use a remark in the right-hand part of a row with a value assignment.
In a value assignment variables can also be used in the value definition as exemplified below:
ColdDataDirectory = /cache/cold ColdInputBaseDirectory = <ColdDataDirectory>/input
The variable <ColdInputBaseDirectory> will eventually be set to “/cache/cold/input” because the variable <ColdDataDirectory>, which must be surrounded by angle brackets, is evaluated so.
The following runtime variables are available during script execution. Although these are not set in any configuration file, they provide values that can be accessed from the runtime environment.
