### CPP_DBG_TABGRID Environment Variable

The CPP_DBG_TABGRID environment variable affects how the debugger uses tab characters to align tabs to columns in a source or mixed view within a Source window. The value of this variable is an integer indicating the starting position and frequency of the tab. For example, if you set CPP_DBG_TABGRID=6, the debugger sets tab stops at 6, 12, 18, 24, and so on. If CPP_DBG_TABGRID is set to a nonzero value, the setting of CPP_DBG_TAB has no effect.
