As I understand, DSQL_drop constant presents the FLAG of operation, not ID of operation.

However, in some cases, instead of checking the flag DSQL_drop, used a direct comparison with DSQL_drop

[GDS_DSQL_FREE] [why.cpp]

	if \(option & DSQL\_drop\) // <\-\-\-\-\- OK
	\{
		destroy\(statement\);
		\*stmt\_handle = 0;
	\}

[GDS_DSQL_FREE] [interface.cpp]

		if \(option == DSQL\_drop\) // <\-\-\-\-\- ???
		\{
			release\_sql\_request\(statement\);
			\*stmt\_handle = NULL;
		\}

		if \(option == DSQL\_drop\) // <\-\-\-\-\- ???
			\*stmt\_handle = NULL;
