4.5.2 How to Use a Configuration File
Create a configuration file containing default values of parameters. When
starting OPERA™ with a configuration file use the following syntax:
opera -Exec -Cfg <Name and path of the configuration file>
The configuration file must have the suffix ".cfg".
A combination of both versions may also be used :
opera -Exec -Cfg DefaultPara.cfg -Input Inp=0
The corresponding setting made in DefaultPara.cfg is overwritten by the -Input
command in this instance.
Comments can be inserted in the configuration file using the character ";" at the
beginning of a line.
