the display. Below this are toggle buttons that show the status of the Breakpoint and
Trace debug functions. You can move the contents of the display to a requested
point in the program through the Find and Goto buttons. A Font selection allows
you to display large, medium or small fonts and consequently fewer or more lines in
the main portion of the display. The main portion of the display shows a listing of
the sequence source statements as they were written using the TCL Editor, and an
executable line number for each statement. Note that the Sequence Source field will
appear if an alias is used. At the end of the listing, TCL Compiler Summary and
TCL Linker Summary information is included.
Choosing a Sequence for Debug Display
A listing of TCL sequences is provided when you first enter a MOD Sequence
Debug display. Choose the sequence to be loaded from the list on the Sequence List
display, Figure 35 (typical).
Sequence Source
The message “Unable to read sequence source.” is displayed when opening the
Sequence Debug display if the source is down, such as when AdvaBuild is not on-
line, or when batch uses an alias for the sequence. If an alias is being used, type the
sequence name in the Sequence Source box, Figure 38, and press Enter to view the
TCL program. If necessary, bring the sequence source on-line and then enter the
sequence name.
An alias is automatically created when a sequence is used twice on the same unit.
The Sequence Source box allows you to resolve which sequence is to be used. Used
within batch, aliases allow an additional copy of a TCL program to be loaded to a
unit without having to duplicate the program in the catalog.
Changing Sequence State, Mode, and Status
Select state, mode or status conditions from the pull-down lists to make changes.
Sequence Debug Program Functions
Sequence debug program functions include trace and breakpoint definition. In
addition, you can use Find and Goto to
