On Universe LIST.LOCKS shows task locks (i.e. LOCK 5 in UVBASIC )- I
have to use LIST.READU EVERY to get readu locks. Does UniData have a
LIST.READU command?

Subject: [U2] Locks, releases and STATU() (oh my)

Hello wizards,

I've read what I can find on the subject, but I'm not finding what I
need.
As usual, anyone who knows where the info is, I would not be the least
bit
offended if you just point.  Or if you know off-hand ...

(Presently grappling with Unidata):

When I hit a lock with a:
READU this FROM that,ID LOCKED locked clause ELSE whatever 

LIST.LOCKS from TCL has always been worse than useless for me.  For
example
at this exact moment I'm holding locks on 3 sessions, yet if I run
LIST.LOCKS on a 4th session it displays ABSOLUTELY NOTHING.  

I don't see much on offer in the LOCKED clause, although the online help
suggests that STATUS() will return the user number of the lock it ran
into.
Can't understand its output... I have a very short program that displays
STATUS(), opens the file and displays STATUS() then does a READU against
an
item I purposefully have locked on another session and I display
STATUS()  a
third time.  What do you suppose its giving me, and what can I do with
it?

1 STATUS = 0     <-- beginning of program
2 STATUS = 1     <-- after the open
3 STATUS = 197613 <-- this is what it gives me after the READU against a
locked item

What I want to do is determine who/what has the lock, tell the user, I
also
want to be able to carry on under my own conditions when ud 46 flag is
set
which will by default allow edits to items I've locked against my own
session.  Which is too loose -- I want to check to make sure I'm in the
exact right condition to do that and I'm not sure how I can (by seeing
what
is holding the lock) but ... does anyone know how to get ANY information
out
of a lock?

Susan
