Description

This statement attempts to lock the current record. If the record is already locked by another user, the procedure displays a dialog and waits for the record to become available.

let ReceivedQuantity=""
gettext "How many "+Item+" were received?",ReceivedQuantity
ReceivedQuantity=val(ReceivedQuantity)
LockRecord
if error
    message “These items could not be added to the database quantity. “+
        “Be sure to process them again later.“
    rtn
endif
Qty=Qty+ReceivedQuantity
UnlockRecord

If you don’t want the code to wait if the record is locked, use the lockorstop statement or the lockcurrentrecord( functionn.
