GTM>; Lock command

GTM>; Example

GTM>; Lock the patient file (there is deception trick here):

GTM>L +^DPT

GTM>L -^DPT

GTM>L +SAM

GTM>L -SAM

GTM>ZED "KBANLOCK"

GTM>zl

GTM>zp ^KBANLOCK
KBANLOCK ; 3/14/11 5:48pm
 ;;
 LOCK +^SAM
 SET ^SAM=1
 LOCK -^SAM
 QUIT


GTM>D ^KBANLOCK

GTM>ZED

GTM>zl

GTM>rec zp

GTM>zp ^KBANLOCK
KBANLOCK ; 3/14/11 5:49pm
 ;;
 LOCK +^SAM
 SET ^SAM=1
 HANG 20
 LOCK -^SAM
 QUIT


GTM>D ^KBANLOCK

GTM>D ^KBANLOCK

GTM>SET TEST=1

GTM>LOCK:TEST ^DPT

GTM>LOCK -^DPT

GTM>LOCK +^DPT:5

GTM>; colon argument means that:

GTM>; Wait for 5 seconds before giving up!

GTM>LOCK +^DPT:5

GTM>W $TEST
1
GTM>LOCK +^DPT:5

GTM>LOCK  ; lock without argument

GTM>; releases all locks a process holds

GTM>LOCK +^DPT:5

GTM>; :5 --> Wait five seconds to try to get the lock.

GTM>; If you still can't get the lock, set $test to false.

GTM>; Old lock syntax, plus a variation on the new syntax

GTM>LOCK ^DPT:5

GTM>; No plus sign

GTM>; Acquires one lock, and unlocks all others

GTM>ZSHOW "L"
MLG:10,MLT:1
LOCK ^DPT LEVEL=1

GTM>LOCK SAM:5

GTM>ZSHOW "L"
MLG:11,MLT:1
LOCK SAM LEVEL=1

GTM>; If I use the plus sign:

GTM>LOCK +^DPT:5

GTM>ZSHOW "L"
MLG:12,MLT:1
LOCK ^DPT LEVEL=1
LOCK SAM LEVEL=1

GTM>; How would you lock more than 1 node if you are using the old syntax?

GTM>LOCK (^DPT,SAM)

GTM>LOCK (+^DPT,+SAM)
%GTM-E-VAREXPECTED, Variable expected in this context
        LOCK (+^DPT,+SAM)
              ^-----

GTM>LOCK (+^DPT,+SAM)
%GTM-E-VAREXPECTED, Variable expected in this context
        LOCK (+^DPT,+SAM)
              ^-----

GT

GTM>LOCK (+^DPT,+SAM)
%GTM-E-VAREXPECTED, Variable expected in this context
        LOCK (+^DPT,+SAM)
              ^-----

GTM>LOCK +(^DPT,SAM)

GTM>ZSHOW
+1^GTM$DMOD    (Direct mode)

GTM>ZSHOW "L"
MLG:14,MLT:1
LOCK SAM LEVEL=2
LOCK ^DPT LEVEL=2

GTM>; Locking a list of variables in () means that you have to be able to lock

GTM>; all of them at the same time, otherwise, it won't work.

GTM>L -^DPT

GTM>L -^DPT

GTM>; Locking any name will lock all its decendants

GTM>; so if you lock SAM

GTM>; you cannot lock SAM(1) in another process

GTM>; however, you can lock SAM(1) in this process

GTM>; and lock SAM(2) in another process

GTM>; because SAM(2) is not a decendant of SAM(1)

GTM>; but you cannot lock SAM(1,1)
