Display Source Lines
Checkbox toggles the display of the source lines, same as the toolbar button "View Source line information" on the Callstack Window.
Number of lines
Choose the number of source lines to be displayed before and after the source line pointed by the program counter. This option is useful when macros are used to define functions or when there are successive calls of the same function, which may lead to confusion as to which function call was made.
Source file information
Choose how you wish to display the source file information. Source file can be displayed with full path, relative path or file name alone.
