Tracking Errors and Using some Common 
Commands 
A window can be displayed which will help you track software errors while your 
are using commands or writing/using macros. The window is accessed with the 
ListMessages command. 
1)  On the command line, type ListMessages On. Notice that a white message 
box is now displayed. The box can be sized differently by dragging the edges. 
Cryptic explanations regarding syntax or other errors will be displayed here as 
they occur. 
2)  Type the following sequence of commands onto the command line. After 
each command line, you may either use the Enter key or use the semicolon,;, 
and the Enter key at the very end of the list. Note the message display. 
Delreg chromreg 
Loadsignal dad,b,,chromreg 
IntegrateObj chromreg[1] 
Draw 2,chromreg,6:8 
3)  Move back through the previous commands by using the up and down arrow 
keys. These keys are useful if a typing error has been made and you don't 
want to type the entire command over again.
