*==============================================================
* When an interactive program tries to update a record that is
* locked by another user, often the program doesn't handle it.
* The RPG error routines kick in and give the user a confusing
* error message.
*
* Instead, trap the error and handle it by calling this program.
*
* This program communicates info about a locked record to an
* interactive user telling who has the lock.
* See program RCDLCKDEMO for a usage example.
*
* RCDLCKDSP accepts a continuation reply from the user and
* passes it back to the caller.
*
* If the status is not 1218, then it is considered an
* unexpected error and a slightly different dialog is
* presented, asking the user to contact IT. You can
* customize this as you see fit. Or add other statuses.
*
* Information is retrieved from the *PSDS passed from the caller.
*
*==============================================================
* Parameters
* ==========
* 1 Output CL1 User's reply about what to do:
* R - Retry the IO operation that failed
* C - Cancel the program
* D - DUmp the program and cancel
* 2 Input * Pointer to the *PSDS in the calling program.
* (A pointer is used because the *PDSD is not
* always the same length in a program.)
*==============================================================
* Create with CRTBNDRPG
* New activation group so we destroy nothing in the caller.
* No worries about overhead since rarely called.
h OPTION(*NODEBUGIO: *SRCSTMT)
H DFTACTGRP(*NO) ACTGRP(*NEW)
