The DBG_SELECT_INTERNAL environment variable forces an exception on the specified condition.


One of the following:

64 = Find Selects that no longer optimize.

128 = Find Select key mismatches.


DBG_SELECT_INTERNAL affects the behavior of DBG_SELECT, to aid in the debugging of a type mismatch. When DBG_SELECT_INTERNAL is set to 64, a type mismatch during the Select that would cause optimization to be disabled will instead throw an $ERR_INVOPER exception that can be used to locate the situation. Setting DBG_SELECT_INTERNAL to 128 causes the exception to be thrown on a mismatch even when optimization still occurs due to a secondary key. These options can be set regardless of the setting of DBG_SELECT.
