 %ERROR
If an 'E' operation code extender is present on the calculation specification and error indicator is not present
then the error occurred will be handled by this operator extender ‘E’.
The errors in this case are identified using the function %ERROR built-in function.
But this operator extender’s use is limited only to the op-codes listed below:
ACQ
ADDDUR
ALLOC
CALL
CALLB
CALLP
CHAIN
CHECK
CHECKR
CLOSE
COMMIT
DEALLOC
DELETE
DSPLY
EXFMT
EXTRCT
FEOD
IN
OCCUR
OPEN
NEXT
OUT
POST
READ
RAEDE
READP
READPE
REL
RESET
ROLBK
REALLOC
SCAN
SETGT
SETLL
SUBDUR
SUBST
TEST
UNLOCK
UPDATE
WRITE
XLATE
XML-INTO
XML-SAX
The error will be handled using the built-in functions %STATUS and %ERROR.
Control resumes with the next ILE RPG operation.
