functionality is similar to the dialog discribed in menu item Ð º ÇÔÒººº. Figure 2.6
shows an example of the ÄÓ ÁÑ Ð dialog.
Figure 2.6: The dialog window to load an image.
After selecting a file name, the name of the variable for the image in the HDevelop program
has to be selected. To do this, a small dialog appears after pressing ÇÔÒ or double
clicking a file. For easy handling, HDevelop suggests a name derived from the selected
file name. You may adopt or edit this name. If you want to use a name of an already
created iconic variable, a combo box offers you all iconic variable names. To do so, you
click the button on the right side of the text field. Note that the reuse of a variable name
deletes the old content and replaces it with the new image.
Ð º ÐÒÙÔ
The menu item Ð º ÐÒÙÔ deletes all unused variables (iconic and control data).
These are variables in the variable window that are no longer used in any operator of the
program. This can happen after the deletion of program lines or after editing variable
names, because the corresponding variables are not deleted automatically. You may use
this menu item during a longer editing process to reorganize your variable window (see
also page 53).
Ð º ÇÔØÓÒ׺ºº
The menu item Ð º ÇÔØÓÒ׺ºº opens a control window, which you can use to
modify output behavior during runtime (see figure 2.7).
¯ ÍÔØ È
The first item (see page 48) concerns the display of the current position while running
the program. The so called È (Program Counter) always indicates the line
of the currently executing operator or the line before the next operator to execute.
