# LINESPEC is a list of the form:

# { DEBUG_FILE FUNCNAME FILENAME LINE }, where:
|
|
#
|
|
# DEBUG_FILE - is the abbreviated form of the file name. This is usually

# the file name string given to the cc command. This is

|
# primarily needed for breakpoint commands, and when an
|
|
# abbreviated for of the filename is desired.
|
|
# FUNCNAME - is the name of the function.
|
|
# FILENAME - is the fully qualified (absolute) file name. It is usually
|
|
# the same as $PWD/$DEBUG_FILE, where PWD is the working dir
|
|
# at the time the cc command was given. This is used to
|
|
# actually locate the file to be displayed.
|
|
# LINE - The line number to be displayed.
|
|
#
|
|
# Usually, this procedure will just move the cursor one line down to the
|
|
# next line to be executed. However, if the cursor moves out of range
|
|
# or into another file, it will scroll the text widget so that the line
|
