// ==============================================================
// 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.
