ONERROR

Some statements in EASI allow the programmer to trap errors through the use of the ONERROR statement suffix. The general form for statements which accept the ONERROR suffix is:

 [statement1] ONERROR [statement2]

where

 statement1 is a statement that supports the ONERROR suffix.
 Statement2 is any valid EASI statement to be executed only if
            an error occurs while executing statement1.

Statements which support the ONERROR suffix are:

• LET (assignment)
• ASK
• RUN
• CALL
• DELETE
• EVAL
• INPUT

ONERROR is also a part of the TRY command (see TRY).
