'*---------------------------------------------------------------------------
'*  Full Screen Text Editor for RBBS-PC
'*  QuickBASIC v3.0 Version
'*  02-16-91
'*
'*  v2.1xx ... made it work with RBBS v17
'*  v2.2 ..... fixed some inconsistincies in the code as to # of lines in msg.
'*             Some of the code thought 99 was length, some thought 100.
'*  v2.3 ..... let it work with quoted reply.  No more REDIM of ZOutTxt$
'*  v2.4 ..... removed tabs, margins code to be smaller
'*  v2.41..... fixed bug with loss of bold attribute occasionally
'*  v2.42..... made it work as a v17.3 subroutine.  Added block delete.
'*  v2.43..... Added to: and from:.  Made cursor keys work locally.
'*  v2.43a.... Stupid little bugs fixed
'*  v2.44..... Fixed bugs, added ^T, Import, Subject, ASM functions
'*  v2.44a.... Wordwrap/reflow bug fixed.  Arrows work in del.  Lines renum.
'*
'*  Returns:
'*  ZSubParm  =  1 - Save Message
'*            =  2 - Abort Message
'*            = -1 - Dropped Carrier
'*            = -2 - Sleep Disconnect
