**''$CSET''** ''[[name|<Name>]]=[[boolean|<Boolean>]]''\\
**''$CSET''** ''[[name|<Name>]]''\\
\\
**''$SET''** ''[[name|<Name>]]=[[boolean|<Boolean>]]''\\
**''$SET''** ''[[name|<Name>]]''\\


This commands sets the option value ''<Name>'' to the value ''<Boolean>'' , or, in the second form, without a value, they set it to True.

The **''$SET''** command stores the value always, the **''$CSET''** stores it only, when the option for the conditional evaluation is not defined yet.

Normally the option values are defined by the **''[[opt|$OPTION]]''** command, and set by the user in the Option menu of the configuration window. There is two reason to set an option with the **''$CSET''** command:

  * to build values derived from the real options
  * to set a value even if the option is not defined.

This second is the case, if you have a complicated timetable consisting of many different files, which are included into a main timetable file or into each other. If you want to test an included timetable file without the main timetable file, you won't have the options, which are specified in the main timetable file. There are two ways to solve this problem:

  * to put all the **''$OPTION''** lines into a special file, which in included in all other files by **''[[require|$REQUIRE]]''**, 

or to give default values by the **''$CSET''** command for that options in each timetable file, which are used there.
