Using Path Substitution

Instead of specifying the full path to data files in your system, you can use path substitution.

With path substitution, you define a name that is a substitution for the full directory path. You can then use the substitution name in the following format:

File Name

[SUBSTITUTION]:<filename>

For example, if you decide to store a trend data file called MYFILE in a directory called C:\CITECT\DATA\MYTRENDS, you can specify the full path to the file, for example:

File Name

C:\CITECT\DATA\MYTRENDS\MYFILE

or define a path substitution (for example MYDATA) and specify the path as:

File Name

[MYDATA]:MYFILE

Path substitution provides greater control of data storage. You can change the location of data files by changing the definition of the data path - instead of locating and changing each occurrence of the data path.
