Re: Re-opening files

[OkAnnie@xxxxxxxx]

"I thought that I would be switching to the log/restore feature
that was added to Xy4, but I find that so far I still prefer my
homegrown concoction.
[...] I originally had the program itself linked to STARTUP.INT,
but decided to separate them, so that I could easily run RESTART
at any later time as well." --Wolfgang Bechstein 

Wolfgang: If you consider imitation a compliment, consider
yourself complimented.

I lumped all shutdown/startup stuff into a single file named !!!
some time ago when I wrote code that at shutdown records which
subdir is active in each logical partition and the active drive
letter to @F, and stsgt's old.!kh. Of course at startup !!!
ldsgt's old.!kh, and all things being equal each subdir and the
drive are reactivated. I always avoided the issue of reopening
the file(s) I was working on at end of session till your
interesting msg inspired me.

My startup.int does two things only: searches a file my
autoexec.bat generates (if trouble found quits xyW; else kills
file), and--using a unique argument--calls !!!. !!! configures or
reconfigures xyW according to what was happening at the end of
the last session and which cartridge hdd is loaded at startup, or
any time !!! receives certain args (for specialized work--QXP,
html, C--.kbds, .hlps, etc.), plus it has all file and session
shutdown stuff.

The shutdown part borrows the Leading Edge Word Processor's 
key concept
(could as easily be ^Q): If I hit  with a file open and
confirm with XC, the file is stored. With no file open,  ...
XC ends the session; if a file is unexpectedly open in another
window, !!! displays it and exits (if I've forgotten it I probably
need to inspect it). Over time I've gilded
LEWP's  lily:  ... CC with file open: (do .exe that)
saves file with no eof.
 ...  with file open: aborts.
 ...  with no file open in active window: closes
window.
 ... <-> in all circumstances: shells to dos.
I've resisted the temptation to overdecorate ( ... 
is *not* close and print file, etc.). Any other key after 
produced no action till I thought about your msg. Now ...

 ... <*> with a file open in any window assumes that the
intent is to preserve the file(s)-open state for the next
session. It uses save/gets @1-@9
(I never ever use @0-@9, or have even as many as five windows
open). !!! cycles through all open files--displays each, records
cursor position and path\name to the @ that corresponds to
windows #1-#9, issues a BC sa ???
(with a clear or execute prompt) {rc}, and aborts. Then the
session shuts down as always. Whether or not @1-@9 are used, !!!
must initialize them all to prep for startup: If !!! finds then
that the size of any is >0 and the content is an existing file,
!!! opens it in the window where it was before and jmp's to the
cursor position recorded in the same @. !!! remove's @1-@9;
old.!kh stays. They are the only files involved (v3 !!!=4366 bytes / v4=4433
/ old.!kh=375 just now). If I decide at startup to do something
else, aborting the open files is simple enough. To restart, I'd
run !!! with the same arg that startup.int sends it. Or I could
code in, say, an r arg so a BC run !!! r XC would skip everything
except the startup @1-@9 stuff. ...

"That's it. As they say, I don't know 'bout you, but it works for
me."

Thanks for the energizing msg, Wolfgang. No doubt any number of
v3 session-saving xpl utilities are floating around. I know
without looking that
Carl's and Robert's are elegant. After I finished mine I
consulted the oracle and found that this time I didn't reinvent
Tyson's wheel (like you, he saved the info to a disk file). I
remembered a save-all-open-files-and-quit sequence in Art
Campbell's v3 alphabetical reference. Who should the author be
but ... Tim Baehr , who started this topic longer ago than I'd
have given him credit for if I hadn't found QUITSAVE in
Campbell's Programs appendix. ;) ... In case it's of interest to
anyone, I'm including the !!!
@1-@9 sections (xyDos 3- and 4-compatible; plus code to protect
@1-@9 from unwanted overwrites) below, PKZIP'd and XXBUG'd.    --A
