2030.0. "ACCVIO whilst executing MCC script under DTM" by TOOK::FONSECA (I heard it through the Grapevine...) Mon Jan 06 1992 12:18

We are trying to get DTM scripts running to test TSAM, and I have
been seeing a strange ACCVIO when the script is run.

First let me explain that how we cause MCC to execute the commands
is a bit unusual.  A temporary file is created which sets up our defualt
entities, and qualifiers, the last statement is a DO file_name.mcc.  This
file contains all of the commands we wish to test.  Then the mcc_init logical
is defined to point to this temporary file.

I had thought that we were defining the MCC_FCL_PM_LOG to 40, but did a 
quick check and discovered that we are not.  In any case that just
prevents the mcc version banner from being displayed.

We are only testing under VMS on MCC 1.2.4.  Here is the portion of the
log file with the ACVIO (by the way the test appears to work, once the
ACCVIO has occured, MCC runs our test fine.)  I am having problems getting
DTM to go from the first test to the next one in the collection, and
it is unclear whether that is due to this or some other problem.  By
the way, I have tried to reproduce this problem by running all of the
scripts interactively, and in batch without involving DTM, and have
been unable to get the ACCVIO to occur.

....things work fine after this (except for my DTM related problems...)

BTW TEST_ROOT:[TEMPLATE]RUN_MCC.COM looks like this:

$       set verify
$       manage :=       manage
$       manage/enterprise       ! Start MCC & execute mcc_init
$       exit



Thanks,

OOOPS, massive stupidity on my part caused this problem...

An ACCVIO I knew about in our code was causing this.  
Compounding the problem was the epilogue & the next test's prologue
go into mcc without deassigning the mcc_init logical which contained the
test script, so I was seeing the ACCVIO in places I had not expected to 
see it, and so on and so on...

I resolve to have no more Mondays like that for the rest of the year!
