// | TO-PRMPT.MPS : RELEASE 2 |-----------------------------------------------
// `--------------------------'
//
//  This mod is was originally written for use with Mystic BBS v1.07.3 by
//  Testoverride, based on some demo MPL code written by g00r00.
//
//  It has been updated for Mystic BBS 1.10+ by g00r00, and released without
//  Testoverride's assistance.  This is not an intentional thing, but TO has
//  been missing lately, so given the circumstances, I think it's okay.
//
//  You are free to modify and do whatever you'd like to with this code, but
//  please if you do make significant changes please let the original authors
//  know so that we can include it into our release if it is worthwhile.
//
//  The code itself isn't as pretty as it could be since MPL has evolved over
//  time, but it is still functional and seems to be widely used.
//
//  The original authors contact info follows:
//
//    Testoverride - testoverride@comcast.net
//          g00r00 - mysticbbs@gmail.com
//
//  New updates for 1.10:
//
//    - Converted to new MPL 1.10
//    - Changed the s255 ACS check to use the message owner MCI code instead
//    - Added the 'H' command to the message reader prompt (set lastread)
//    - Added the 'M' command to the message reader prompt (move message)
//    - Added the 'F' command to the message reader prompt (forward)
//    - Some conversions of IF statements to CASE statements for code clarity
