Subject: VERY Important Message!

Hi, All! ========= IMPORTANT ANNOUCEMENT =========>

Finally, PostIt! 6.0 will be posted. I won't repeat the new features,
but they can be found in PostIt!'s header.

It is =ESSENTIAL= that you capture the next 16 messages. From this
now on, PostIt!'s scripts will not be able to be decoded by QuickBASIC
alone. It will require PostIt! 6.0 to extract the file.

The new format is so much more compact -- primarily due to the removal
of the decoder. It was pretty wasteful to post the decoder again and again,
with every binary file. That's why it has been incorporated into PostIt! 6.0.

You may wonder why this release is 16 messages long. That may sound like
much, but it isn't! The line length has been shortened to =65= and page
length to =85=. All that contribute to more line wrapping, thus increasing
the number of posts. The 'real' file size of PostIt! 6.0 is only 1K bigger
than 5.1. Why '65'? To make sure all people will recieve PostIt! without
things being truncated.

I really hope the complete PostIt! package reaches everybody reading this
echo. I am excited to post my latest additions, so here it is.....

Victor

'
' PostIt! THE Binary <-> BASIC Script Creator
'
' * * *
'
' Postit! v6.0 by Rich Geldreich 1992
'
' Decoder further optimizied by Jim Giordano
'
' User Interface and Graphical embellishments by
' Mark H Butler & Quinn Tyler Jackson
'
' Ability to post and wrap plain code - as text!
' Based on MsgSplit by Scott Wunsch and Victor Yiu.
'
' And now, with compression and a new script format
' to reduce the echo bandwidth required to post your
' file, from Victor Yiu!
'
'
'Purpose:
' To enable the posting of compressed listings on a text only net.
' This program takes a binary input file and converts it to a series
' of small, postable files which other people can capture and run to
' get the original binary file.
'
'Instructions:
' Just follow the prompts. You give the input & output filenames,
' the page length and the number of lines you want reserved for your
' stuff and it does the rest. If nothing is inputted for a prompt, a
' default value will be used for it instead.
'
'
'Additions by Victor Yiu:
'
' (26 March 1993)
' NEW! Addition of the new high efficiency script format, saving
' 800 bytes over the old format! Still supports the old self-
' extracting model for compatibility. New format allows you to
' run the cut script from the echo without editing! Just paste
' all the pages together and run it through PostIt!.
' Now, all line lengths will remain constant, even with compression.
' It results in less unnecessary carriage returns and `G"' lines!
' After this update, I don't see too many improvements ahead -- it's so
' jam packed with features! 😉
' Some unnecessary & ancient comments are removed for space efficiency
' The source is also modified so that most lines are less than
'

' (16 March 1993)
' Victor Yiu nominated & appointed the keeper of PostIt! by Zack Jones.
'
' (9 March 1993)
' Version 5.1 speeds the binary decoder up and cleans the PostIt!
' source code enormously. Decompression routine rewritten.
' Message splitter's tab stop expansion is now user modifiable.
'
' (28 February 1993)
' Now, save an average of 10% on posting object files! This version
' includes compression of duplicate characters. Also fixes several
' bugs and quirks (visual & operational), and adds a disk buffer for
' increased conversion speed. The text wrapping problem with
' quotes has also been totally elimintated; now, the comments
' starting later in the line extending past the wrap will not be
' messed up during splitting, as is was before. Twirler was
' optimized/fixed (MsgSplit). Decoder was optimized more, but more
' code had to be added on to handle compression.
'
'Additions by Scott Wunsch:
' (13 February 1993)
' PostIt! is no longer just for binary files! It can be used to post
' BASIC code, and will do so in text format. Code will be word-
' wrapped appropriately, and underscores inserted to allow QB/PDS to
' put it back together again for you. Unlike past code-wrapping
' programs, PostIt! can even handle quoted strings properly.
'
'Additions by Mark Butler:
' (8-30-1992)
' Postit! output filename now defaults to the input filename if none
' is given. If the input filename is 8 characters in length the
' default output filename will be truncated to the first 7 characters
' of the input filename. The default output extension is now "BAS"

' instead of nothing. I also added a little bit of text mode "screen
' magic" to further augment Quinn T. Jackson's copyright screen and
' warning screen additions. Fixed bug from version 2.8 that caused
' succeeding output files after the first one to overwrite the same
' filename due to the filename number suffix not incrementing. I also
' caused the program to skip the opening screens if an input filename
' is entered from the command line when the program is run. (I didn't
' think folks wanted to see those screens *every* time they wanted to
' use PostIt! Sometimes ya just want to get on with it right?)
' (9-1-1992)
' Hardcoded a CHR$(32) (a space character) to the end of each full
' length G-sub data line in the attempt to thwart line truncation in
' transit on the Net. Just a theory that I hope is correct! -> MHB
'
'Additions and Modifications by Quinn Tyler Jackson (August 22, 1992):
'
' Postit! now prints a warning screen, warning users of possible
' abuse of binary-to-text posts. Also, instead of the old '80% DONE'
' meter, this version uses a graphical bar that looks like this:
'
' (One block=2% completion.)
'
' I have also added a nice starting screen, giving Rich credit where
' it is due! Bells and whistles, boys!
'
'
'Note to QBasic users:
' The COMMAND$ function is utilized in this version so if you are
' using QBasic you should delete the lines marked "**** Delete this
' line for QBasic use ******". All such lines *MUST* be deleted or
' REMmed out for this version to work with QBasic.
'
'Note: The decoder outputted with the encoded data has been
' "compressed" in order to squeeze it into 8 lines. Each line of the
' decoder is less that 72 characters, so don't worry if it looks like
' some lines are too long when you load it into QB. When QB expands
' the decoder to make it look "nicer," some lines will look like
' they're too long to put on an echo, even though they aren't. What
' I'm trying to say is: Only post the files outputted by this
' program, don't load them into QB and resave them.
'
'Tech stuff:
' The output files created by this program should be "echo safe".
' The following 64 characters are used to encode the binary file:
'
' abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789()
'
' The script file is checked at runtime to see if all of the encoded
' data is present. Also, a simple checksum is used to inform the
' user if the script file was screwed or not. (The file created is
' not deleted if this occurs, however. If only a few characters are

' garbled, then some of the output file may be still extractable.
' But if the 6-bit output stream falls out of sync, then there's a
' very good chance that the rest of the archive is completly
' unusable.)
'
' If anybody has any suggestions, or finds any bugs in this program,
' then please drop me a message and tell me about it! -Rich Geldreich
