Core Statements

REVERT The REVERT core statement releases (in the current block) the most recently executed
ON block for the specified condition. This leaves unaffected any handler for the same
condition in an outer block, because that handler now becomes the current handler. If
there is no condition handler in the current block, REVERT behaves as a NOP
statement. (The ON core statement, described earlier in this section, defines an ON
block.)
REVERT condition
condition
specifies the condition name that the procedure reverts to. See the description of
the ON statement for details on the syntax of a condition name.
Consideration
See also ON, RESUME, RETRY, and SIGNAL. These core statements are all relevant to
condition and error handling. The ON core statement defines an ON block, which
determines what you want to do for a specified condition or error. The RESUME core
statement ignores the statement that generated the condition or error. The RETRY
core statement retries the statement that generated the condition or error. The
SIGNAL core statement generates a condition.
