Writing

Loading complete

4. Unassembling Memory

Confirm that you have loaded the 'Looptest' file satisfactorily by unassembling it. Type (upper or lower

case):

U FB00 FB1E <enter>

Compare the listing in the output window with that in the LOOPTEST.LST file which is also in the

\Samples\ subfolder.

5. Unassembling with Labels

Open Settings>Debug, and check 'As last loaded S19 file' in the Symbol Table panel. Close Settings

by clicking the 'OK' button. Recall the previous unassembly command by hitting the up arrow once.

Hit <enter>. Now the listing should include the symbolic label information for 'Looptest'.

You may view the currently-loaded symbol table by clicking 'Symbol Table' in the View menu. The

symbol table display may be adjusted for height, and moved to some other part of the screen - its

layout will be remembered in the Windows Registry for the next time it is used.

6. Verifying Memory

You can also verify a loaded program by using the Verify command (page 66). Click on

Actions>Verify S19... (in the main menu), and select LOOPTEST.S19 again in the file-open dialog.

This should produce the message 'MCU memory verifies OK' in the output window.

7. Running a Program

Type:

G FB00 <enter>

The status line will change briefly to 'Running' and then back to 'Monitor Mode'. The LOOPTEST

program ends with an SWI which is why it returns to monitor mode. Depending on the selections in

Settings>Debug the output window will display information on the instruction and registers at the

starting point, $FB00.
