;THE FOLLOWING CONVENTIONS ARE OBSERVED FOR OUTPUT ON THE ERROR
;FILE: 1. IF THERE IS A LISTING DEVICE, THE ERROR IS ALWAYS
; OUTPUT ON THE LISTING DEVICE
; 2. IF THERE IS NO LISTING DEVICE, THE ERROR WILL BE
; TYPED ON THE CONSOLE TTY, AND THE ROUTINE EXITS
; 3. AFTER THE CHARACTER HAS BEEN OUTPUT ON THE LISTING
; FILE, THE CHARACTER WILL ALSO BE OUTPUT ON THE TTY
; UNLESS ONE OF THE FOLLOWING CONDITIONS EXISTS:
; A. THE USER HAS REQUESTED THAT ERRORS BE SUPPRESSED
; B. THE LISTING FILE IS ITSELF A TTY.
; 4. IF CERTAINS CONDITIONS OCCUR,THE MESSAGE "SOURCE
; ERROR(S) IN FILEXXX " WILL BE TYPED OUT BEFORE
; THE ERROR CHARACTER IS OUTPUT. THESE CONDITIONS
; ARE:
; A. THE COMPILATION IS IN STANDARD MODE (I.E. ,
; ONE OF MANY COMPILATIONS FROM THE SAME
; COMMAND STRING).
; B. THE INPUT IS NOT ON THE TTY
; . THE USER HAS NOT REQUESTED SUPPRESSION
; OF ERRORS WITH AN N SWITCH
; D. THE MESSAGE HAS NOT BEEN TYPED BEFORE
