211.0. "ACCVIO using MAIL READ in BATCH mode" by EVENS::NUTKINSM (Martin Nutkins) Wed Mar 11 1992 00:26

	I am having a problem using the MAIL READ command in batch mode which
	results in the infamous ACCESS VIOLATION message.  I gather from
	other notes that this is not unusual for mail commands in batch.

	I have tried various alternative ways including using a MAIL GET first.

	Am I doing anything wrong ?  

	Any suggestion/workarounds on the following :-


	AW.COM

	$ allin1/noinit/username="nutkinsm"
	oa$ini_init
	do aw.scp
	exit


	AW.SCP

	! AW.SCP
	!
   oa$tra_set form,field,mess,put,symbol,log,flow,all,a1log,input,script,scrchr
	.trace
	get #x = "INBOX                         012864"
	mail init
	mail read #x
	get #title = oa$curmes_title
	mail file_body #title,"TEMP"

	
	A1TRACE.LOG

    Martin,
    
    MAIL READ - a beautiful piece of code well apart from the Voice Mail
    stuff and the metering and the ... (:==:)
    
    Your example worked fine for me when I tried it (v2.4 and v3.0) but then I
    have NEVER seen the MAIL code ACCVIO (I always kept my eyes shut)
    
    Regards,

    Martin,
    
    You might emulating the MAIL READ by resetting the the status flag 
    to READ, decrementing the unread mail count, and then refiling the
    message to the READ folder (assuming it starts out in the INBOX).
    
    Tryin' to help,
    
    Jack
    

    Could it be that you are attempting to read a WPS-PLUS message?
    WPS-PLUS gets upset when used non-interatively.
    
    Try it with an ASCII mail message.

    Well I didn't have any success with the MAIL READ in BATCH.  It gave
    the same error on both the customers development and live systems and
    also on our ALL-IN-1 system in the office.  I also tried both ASCII and
    WPS-PLUS messages.  Yet the Customer Support Centre could not replicate
    the problem.
    
    I was also experiencing a 'ACCESS VIOLATION' error with the the MAIL
    MAIL_DOCUMENT command, but I managed to get around this using ATTACH
    command.
    
    I got the customers application working in the end, but there must be 
    something different on the customers and the office system that is
    causing this error.
    
    Yet another of life's unsolved mysteries !!!
    
    
    Thanks for you help
    
    
    Martin

    I don't see #X getting used here at all.  Have you tried making the
    document current first?  The symbol is parsed on the line above, but
    that doesn't necessarily mean MAIL READ uses the value.  You could use
    MAIL PUSH to save the value.
    
    Ben

	Have you tried to change your batch procedure to start Uncustomized
	ALL-IN-1 ($ALLIN1/NOINIT/NOCUSTOM/USER...) to restrict the problem
	outside Digital supplied base code.
