NO-LOCK, EXCLUSIVE-LOCK, SHARE-LOCK, and NO-WAIT are ABL keywords that also represent constants that you can assign to an integer variable and pass in as an integer to the FIND- and GET- methods. For example:
VAR INTEGER iLock.

iLock = EXCLUSIVE-LOCK.
hBuffer:FIND-FIRST(“CustNum = 5”,iLock).

This can be useful when the FIND or GET method is in a different procedure or function from the one that determines what the lock or wait mode should be, or when you want to enumerate these lock and wait options and pick one depending on some other value.
