The locked clause is used when the requested
item is locked and waiting is not desired.
Syntax
locked statement.block
Description
Note: You can specify the amount
of time a process waits to execute the locked clause
in the FSI if a lock is present by creating the updLockTimeout registry value in the HKEY_LOCAL_MACHINE/SOFTWARE/RocketSoftware/D3/CurrentVersion/D3FSI/ directory in registry. If this value is not explicitly specified,
the default update lock timeout is 500 milliseconds.
Example(s)
read cust.item from fv.cust,ID locked print ID:" is locked by port ":system(0)
