You mean you want to loop on the checking *until* the lock is released and then
write?
So this is for a job interview?
DOLOOP = 0
LOOP
READU ITSLOCKEDJIM FROM Y,Z LOCKED
DOLOOP = 1
END
UNTIL NOT(DOLOOP) DO
SLEEP 10; *Let the system catch its breath
REPEAT
WRITE X ON Y,Z ELSE CRT 'HELP ME! HELP ME!'

Subject: [U2] Record locks (Unidata 7.2)
Hi all,
I have not looked at the world of record locks since my R83 Pick days. I'm
hoping to add the ability for the program I'm working on to:
* Check if a record is locked
* Wait until the lock is removed
* Once the lock is removed, or if the record is not locked:
* Lock the record
* Perform the WRITE statement
I'm hoping someone can share an example of how to accomplish this in UniBasic.
Thank you,
Jon Wells
