sion.

mation on how to write your expressions, refer to the Microsoft help on Visual Basic scripting. Click

Using Expression Editor
The labeling software has a simple text built-in editor. You can use it to design your own simple Vis-
ual Basic scripts.
The Expression editor is a programming text editor with constant access to command reference of
the script language you are currently using.
The Expression editor lets you edit your scripts and expressions with ease. The Load and Save but-
tons allow you to import / export Visual Basic scripts from / to external text files. The editor uses
standard shortcuts for positioning of the cursor and working with text files. Standard Search and
Replace shortcuts (Ctrl + F, Ctrl + R) are also available.
The working window is divided into four parts.
Category This section contains the groups of available commands, functions,
and operators. Similar objects have been grouped together for eas-
ier identification and faster search.
The groups are displayed as a tree-view. Select the main group
name to display all its contents into the Name section. Or you can
click the plus sign in front of the group name (if available) to dis-
play all defined sub-groups. Then select the sub-group name to dis-
play only its contents.

Category section. All available commands, functions, operators etc.
