950 | # DEBUG_FILE - is the abbreviated form of the file name. This is usually | |
951 | # the file name string given to the cc command. This is | |
952 | # primarily needed for breakpoint commands, and when an | |
953 | # abbreviated for of the filename is desired. | |
954 | # FUNCNAME - is the name of the function. | |
955 | # FILENAME - is the fully qualified (absolute) file name. It is usually | |
956 | # the same as $PWD/$DEBUG_FILE, where PWD is the working dir | |
957 | # at the time the cc command was given. This is used to | |
958 | # actually locate the file to be displayed. | |
959 | # LINE - The line number to be displayed. | |
960 | # | |

962 | # next line to be executed. However, if the cursor moves out of range | |
963 | # or into another file, it will scroll the text widget so that the line | |
964 | # of interest is in the middle of the viewable portion of the widget. | |
