50 REM changes of 11/14/80 by Ron Fowler
60 REM    ADDED PERSONAL MESSAGE FUNCTION
70 REM    K FUNCTION STORES NAME OF ERASING USER IN MSG# RECORD
80 REM changes of 11/9/80  by Ron Fowler
90 REM  1: PRINT CALLERS FOR SYSOP
100 REM  2: SAVE KILLED MSG #S, PUT PWD'S IN MSG FILE
110 REM  3: RE-ENTRY OPTION, FILE "LASTCALR"
120 REM 10/21/80 --> Fix several minor bugs in P and S cmds.  (BRR)
130 REM Changes 10/15/80 by Ron Fowler:
140 REM    1) added "Q", quick summary command
150 REM    2) added "X", "P" cmds - expert user mode, and bell toggle
160 REM    3) rearranged message entry for CBBS compatibility
170 REM    4) added ";" delimitation - "command anticipation"
180 REM    5) added password file access at 3 levels:
190 REM       a. p1$ is high-level quick-access to cp/m
200 REM       b. p2$ is sysop 'last name' (sysop has special priveliges)
210 REM       c. p3$ is the normal cpm access password:
220 REM          (IF P3$ IS "NOPASS", THEN CPM ACCESS IS UNRESTRICTED)
230 REM    6) coded several sequences as subroutines, to shorten code
240 REM    7) made several cosmetic changes
250 REM note: the file "PWDS" can be created by a text editor.  The
260 REM       passwords are sequential..e.g.,"GOTOCPM,FOWLER,NOPASS"
