[Now I know why he's been ragging me about *my* editor....  ++bsa]

Ok, this is a MUCH needed upgrade to the SBBS editor. Some bugs were fixed.
Make sure that the resulting file help.editor is moved in the sbbs "misc"
directory. This is used with the "?" command. Also make sure you read
README.MOD1 and of course move "edit" to sbbs's "programs" directory.

All future modifications will be released to this news group. Do to some errors
and problems, an SBBS SYSII will be posted to comp.sources.unix at the end
of this year. But after then, any fixes and changes go to comp.source.misc.
The latest version will always be available by my bbs at (216)-781-6201 (login
"sbbs")

X   (R)ot 13 / DeRot 13 a message.
X
XValid Ranges:
X
X    With the E)dit and I)nsert commands, you may include a number AFTER the
Xletter command to stand for a line to apply that command. For instance,
Xto edit line 4 of the message, type
X         e4
X    To insert before line 6, type
X         i6
X
X    For the L)ist and D)elete commands, SBBS accepts a range. A range can be
Xa simple number or a range of lines. It can be used directly after the command
Xor in responce to a question.
X    Valid ranges are:
X
X    n1,n2 (Line n1 through line n2)
X    n1,$  (Line n1 through the end)
X    1,n1  (Line 1 through line n1)
X    1,$   (The entire message)
X    /s1/s2/
X          (The first line containing s1 through the first line containing s2)
X
X    You may also use - and + operators:
X
X    4-1,6+2  (3 though 8)
