In the following example, Command1, Command2, and Command3 are applied if 

the argument xyz is defined. 

#ifdef xyz

 

Command1

 

Command2

 

Command3

 

#else

 

Command4

 

Command5

 

Command6

 

#endif

 

Another way to skip a section is with the #skip directive.  The Command1, 

Command2, and Command3 lines are also not processed in the following example. 

#skip

 

Command1

 

Command2

 

Command3

 

#endif

 

The preprocessor also supports inclusion of other files.  The #include directive 

causes a file to be inserted at the current position.  In the following example, the file 

x.txt is processed.  The file must be in the ConfigFiles directory. 

#include x.txt

 

The special command "exit" causes the current file processing to be terminated.  This 

is the single command that does not require the # character in the first column. 

 

Legacy Configuration File Format 
The legacy configuration file format is only used from a single place on the web GUI.  

On the Configuration Manager - Configuration Files page, the LoadConfigFileName 

entry supports the legacy file format.  Entering a file name here and clicking Commit 

Changes causes the file to be processed. 
The legacy configuration file was designed to create a set of objects, typically 

devices, and preset the state of those objects.  Each line of the file creates an object.  

After the data defining the type of object and instance name, additional commands 

can be appended that preset the state of the device.  Presetting many items requires a 

long command line.  This is handled by supporting a continuation (\) character 

allowing the virtual command line to be spread over many lines in the file.  The 

number of lines is effectively unlimited.  
A command line consists of a set of arguments separated by termination characters. 

An argument is a text string indicating a name or a type.  Termination characters are 

whitespace, commas, and the equal sign.  The semicolon indicates a comment.  Blank 

lines are ignored.
