SPAM-LOW: FW: [HP3000-L] Quick file access behaviour

[Anne Quirke]

Thanks John.

Changing the screen is not an option as we don't have the source code for
the production version nor can we get it..(long story). I may just have to
find another solution.

Thanks

Anne

Sorry to hear you say you can't change the screen -- that may be the
only solution.

If you can change the screen then try changing the file statement in the
screen:
>File YourMsgFile Designer Open Semiexclusive Append

Because Quick wants to hold files open indefinitely, I try to include an
explicit "Close YourMsgFile" after writing to the file, either in the
designer code or in a postupdate procedure.

The same file open is accomplished by the following in Qtp:
>Set File YourMsgFile Open Semiexclusive Append

The file equate for the message file includes the NOLOCK option, as in:
:FILE MSGFILE;NOLOCK

This has been working for me since version 5 -- hope this helps you.

Regards,
JWP

All,

I am looking for wisdom and inspiration after attempting to figure out
whats 
going on with a quick screen that does not like a file reference.

1. I cannot change the quick screen
2. The quick screen has the statement FILE A designer
3. File A is a flat ascii file
4. I want file A to be a msg file so I build (B) an exact copy of A but
add ;msg
5. I then file equate FILE A=B,old;shr
6. The screen ERRORS 
     Data access error. (A)
     OPERATION INCONSISTENT WITH ACCESS TYPE  (FSERR 40)
7. I have tried as many combinations of the file equation as I can think
of
    FILE A=B,old;shr
    FILE A=B,old;shr;acc=append
    FILE A=B,old;shr;msg;acc=append
    etc
8. This issue only arises when B is a msg file. If I create B as a std
file then 
the file equation works.

I have non production version of the screen and if I change the file
statement 
to FILE A OPEN APPEND SHARE the screen works. With the file equation
FILE 
A=B,old;shr

So I was wondering if anybody has some inspiration for me.

Many thanks

Anne
