Catch problem [message #23029]

Recently, I started learning the catch procedure to help with some error
checking. I typed the code word-for-word out of the IDL 5.3
documentation:

PRO ABC

A = fltarr(10)

CATCH, Error_status

IF Error_status NE O THEN BEGIN
PRINT, 'ERROR INDEX: ', Error_Status
PRINT, 'ERROR MESSAGE: ', !ERR_STRING
A = FLTARR(12)
ENDIF

A[11] = 12

HELP, A

END

to help me learn this command. However, this code does not seem to
execute correctly. As far as I can tell, the code causes some sort of
infinite loop on the if statement. Any ideas what I am doing wrong? I am
using IDL 5.4 on a Mac.
