The expression is a one-line Visual Basic script. You can use up to   100 characters for your expres-
sion.

Note: The multi-line   commands like "if..then..else.." cannot be used with the Visual   Basic expres-
sion. You can use one-line expressions.

A Visual Basic expression must follow the Visual Basic script programming   syntax. For more infor-
mation on how to write your expressions, refer to   the Microsoft help on Visual Basic scripting. Click 
on the button 'VB   Script Help' in VB   script step in the Text or Bar Code wizard to open the Micro-
soft help.

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.
