Delete variables
Variables are deleted in the window of selected variables by selecting the appropriate variables
(single mouse click) and pressing the "Delete" key. No deletion action is taken with the double-
click function. It is possible to select several variables for deletion (see Section "Example of
search criteria > Selecting variables").
This action can also be undone under the "Edit" menu item.
Note
Deleting of variables results in a change of the absolute addresses of the pointer structures to
the variables. When changing the variable selection, it is, therefore, absolutely necessary to
generate one or several text files of all user blocksprior to the change. This is the only way to
ensure that the assignment of the variables in FB "GET" or FB "PUT" remains correct, even
after recompilation.
Storing a selected list
Once variables have been selected, they can be stored under a project name. The files are
stored on a project-specific basis.
A window is displayed for the file to be stored. The project path and name for the file must be
selected in the window.
