Subject:  Multi user programming?



Suppose I'm running a program which is used to edit a record.  Now let us say
I'm in edit mode, editing a record.  And when I try to run the same program in
one more terminal and try to edit the same record, which is already used by
one more user, the system shows blank screen with "X" at the bottom.  How to
rectify this problem.  How do the network programming works.  How to lock and
unlock the records.

Can u help me in this regards,

See that N it is for a no lock read on a update file, it works for all File I/O
operations including Chain.


C                     READ(N)  File                 4140


This is ILE style


When the person hits the enter key then you read/chain for the same record again
without the N in the code, move in the changes and promptly update the record.
