Variables
The command “New Variable” can be also called from the context menu at any place of the list of
variables.
Besides the use of the aforementioned method, it is possible to create a new variable by other means. It is
enough to put the name of yet non-existing variable into the expression of some variable. After recalculation
of the given expression the system will find that such variable (for example, the variable “С”) has not been
defined, and a message will pop up on the screen: “Create variable “C”?”. If the question is
answered positively, the new variable will automatically appear in the list of variables, and the focus of input
will be moved to its field “Expression” – for specifying the expression for this variable. In case of a negative
answer, the new variable is not created and the error message is generated.
Creating List of Variable's Values
The list of variable’s values is created with the help of the parameter “Value List” in the variable’s properties
window. The method by which the variable’s list is created is chosen from the pull down menu of this
parameter: “Text”, “Database”, “File”, “Data”, “Materials”.
After selecting the list creation method on the basis of text, the window of the text editor will appear, in
which the necessary list of values can be formed. Each value has to be located in a separate line. Upon
creating the list, all options of the text editor become available.
When the list is created on the basis of database, already
existing internal database is used. For example, let's suppose
there is database shown on the picture. After calling the
command for creating the list on the basis of database, the
dialog window will appear. The parameters for forming the list
have to be indicated in this window.
One has to choose:
- the name of the database from the list of databases for the
current document;
