; FUNCTIONAL DESCRIPTION:
;
; The ISERR function inhibits the monitor from aborting the job and causes 
; instead an error to be returned to the offending EMT.
;    
; CALLING SEQUENCE:
;
;	i =  ISERR ()
;
; INPUT PARAMETERS:
;
; NONE
;    
; RETURNED FUNCTION VALUE:
;
;    i = 0 indicates that IHERR was in effect
;      = 1 indicates that ISERR was in effect

; FUNCTIONAL DESCRIPTION:
;
; The IHERR function turns off user error interception. It allows the system 
; to  abort the job on fatal errors and generate an error message.

; INPUT PARAMETERS:
;
; NONE
