#RAISE Built-In Function

Use #RAISE in a routine to explicitly cause an exception. The exception must be

filtered by some active routine.

exception

can be any of these:

_BREAK

indicates that the BREAK key has been pressed.

_ERROR

indicates that an error has occurred.

user_exception

is any text, 1 to 31 alphanumeric characters in length, of which the first must be

alphabetic.

Result

#RAISE returns nothing.

Consideration

All routines up to and including the one having the exception filter are eliminated, and

the routine that issued #FILTER is reinvoked. You can use #EXCEPTION to deter

mine why the routine was reinvoked. (See the discussion of exception handling in the

TACL Programming Guide and the example fro the #FILTER Built-In Function on

page 9-179.)
