Variables are declared in the top/right area of the Workbench main window.
The variable editor
is a grid tool that enables you to declare all variables of the
application. Variables in the editor are sorted by groups:
- global variables
- "retain" non volatile global variables
- I/O variables (each I/O device is a group)
- variables local to a program (including in and out parameters in case of a UDFB).
Please refer to the description of variables in the language reference for a more detailed overview.
Each group is marked with a gray header in the variable list. The "-" or "+" icon on the left of the group header can be used to expand or collapse the group:
Double clicking the header line enables you to sort, show or hide columns, and to apply a filter for each column. Filter is described as a text string that may contain '?' and '*' wildchars.
