Debugger Icons

The following buttons appear at the top of the BASIC Editor dialog:

To	Click
Continue execution of macro.	Go
Halt execution of macro.	Stop
Toggle a breakpoint.	Break
Execute one line of source and trace execution into a subroutine if necessary.	Step Into
Execute one line of source without tracing execution into subroutines.	Step Over
Opens the Variables dialog box for viewing and modifying BASIC variables.	Variables

Go

Causes macro execution to resume and continue until a breakpoint is encountered or the macro es execution.

Stop

Aborts the currently active macro debugging session.

Toggle Breakpoint

Sets a breakpoint at the source line indicated by the cursor. When the debugger reaches this line during the execution of a macro, it immediately suspends execution and highlights the line in the source code window.

Step Into

Executes the line in the macro currently highlighted by the debugger. If the currently highlighted macro line is a subroutine or function call, the debugger traces downward to the first line of source in the subroutine or function, otherwise the highlight moves on to the next consecutive line in the macro.

Step Over

Executes the currently highlighted line of source code in the macro. Use this option instead of Step Into when you do not want the debugger to trace downward into subroutines or functions.

Edit Variables

Opens the Inspect Variable dialog box which is used to view or set the value of a macro variable.

Code area

Spans most of the BASIC Editor dialog box. When the BASIC Editor dialog is resized, so is the code area. Thus users can increase or decrease the number of visible rows and columns in the code area. The code area allows text strings to be entered and edited and supports vertical scrolling. Control vertical scrolling with a scroll bar that is part of the code area.

Press the <Enter> key to enter a line break. The standard cut, copy, and paste operations are supported. Select multiple characters by dragging the mouse cursor through text ranges and by performing keyboard navigation while holding down the shift key. Horizontal scrolling is also supported. Control horizontal scrolling by moving the cursor to the left or right. As the cursor moves out of the display area, MicroStation scrolls the text so the cursor remains in the display area.

Status Message Field

Status Message Field is a read-only, text field used to display debugger status messages. It is located directly beneath the code area on the left side of the dialog box. Stretch the width of the dialog to expand the field size.

Line Number and Column Number Fields

Line Number and Column Number Fields are read-only, text fields that show the macro program line and column numbers where the cursor is currently positioned. These fields are always synchronized with cursor movement, either from a user key-in (e.g., UP ARROW or PAGE DOWN) or from a macro error during debugging.
