Record locking. was (Re: Question on sending status messages to a RPG program)

[Frank Kolmann <Frank.Kolmann@xxxxxxxxx>]

Never ever code record locks that persist longer than 1 second.
Fix the program holding a persistent record lock to release the lock 
before it displays the next screen panel.
There are far better ways to check for record changes done before the 
update, or simply accept the change from elsewhere.
In 30 years of coding this strategy never failed.
Otherwise one ends up coding all sorts of convoluted constructs that 
always ultimately fail.
