This Manual is simply to explain certain items that pertain to the TSR
version of CREF (CREFR.EXE). All legal and support information can be
construed to be that listed in the CREF.DOC file. All system requirements
are the same as that for the CREF.EXE file.
The TSR version may not be distributed without the command line version. It
must be a part of the overall package CREF11.ZIP as originally distributed.
Now....down to business....
CREFR is a TSR or Terminate and Stay Resident program, which means that when
it is invoked it loads itself into memory and remains there until you reboot
your computer. It waits for its key press, then activates to the front of
any program, where you may view the information it has to offer.
To load CREFR simply type CREFR and press <Enter>. Currently the program
has no option to remove itself from memory. You may wish to use a TSR
management program team such as Install.Com/Remove.Com or
Mark.Com/Release.Com, which are available as Shareware on many Bulletin
Board systems. Another good program is PopDrop which is a commercial
product. If you will use a management program such as these its a good idea
to create a batch file to load the file ie:
REM LCR.BAT {Load Crefr}
@echo off
PopDrop
CREFR
REM End of batch
Thus, one command will set up the TSR manager and load CREFR. Of course you
will want to remove it when you're done, you could create another batch file
to do that or issue the removal command from the prompt. Refer to the
documentation for the TSR manager.
When CREFR loads the screen will clear and a message box will pop onto the
screen telling you the program has been installed. It will also show you the
"Hot Key" combination to call CREFR, which is Ctrl-Alt-R which means that
you hold down the Ctrl and Alt keys together then press the R character key.
The CREFR menu will appear at the upper left corner of the screen, from this
point on the chart selections are identical to that of the command line
version CREF.
When CREFR is called via the HotKey it first does two things, it saves the
underlying Dos or Program screen, and saves the current cursor position.
When you exit CREFR by choosing Quit, it restores the screen and returns the
cursor to its previous position. Now, the cursor reposition does not always
appear to work....some programs that have a horizontal menu bar across the
top will not allow the cursor to return right away. What happens is that the
first Menu Choice will be highlighted....simply press Esc and the cursor
will return to its previous location.
PROGRAM SIZE:
The TSR uses about 57K of memory while it is resident. It has proven
compatible with most Editors and other programs, a listing will be shown a
little later of programs tested. But for instance, it will allow Qedit to
edit a 130K text file without any problems. Depending on your system setup
and how much memory is being used by your setup, the 57K CREFR uses should
not cause any problems.
Currently all the charts used by CREFR are built into the program, should
this program expand (more charts etc) then I may change it to where it will
load charts from an on-disk library. This will cause a *small* speed loss,
but conserve memory use. I do not want to see CREFR get much above a 60K
item in memory....but thats a future issue.
NUMLOCK KEY:
It is STRONGLY RECOMMENDED that you turn off the NumLock key on 100+ key
keyboards before loading CREFR, at times the program seems to lock up if you
don't, it does not handle the NumLock key in a standard way. If things
appear to lock up, before you hit the reboot button, try banging (gently)
around on various key combinations, this sometimes will loosen things up.
** I know it sounds strange...but it often works **
If just after you have loaded CREFR you realize that the number lock key was
on, use the provided LOCK.COM .... first turn NUMLOCK OFF then type LOCK N-
this will reset the NumLock to off status.
LOCK.COM can be used with the CAPS and SCROLLOCK too. Type NUMLOCK by itself
for a command description.
If this won't do it then you may have to reboot.
But don't fret to much, after a little trial and error you will not have any
more problems, I've had them all!
PROGRAM COMPATIBILITY:
CREFR WILL NOT work over graphics programs. If you call it while a graphics
program is running, plan on a reboot!
Following is a list of editors that CREFR has been tested with.
PASCAL TURBO IDE Editor.........OK! QUICKBASIC 4.5.MSOFT......OK!
BOXER by David Hamel............OK! XTREE GOLD.Exec.Systems....OK!
QEDIT by Semware................OK! THEDRAW 4.51 Ian Davis....OK!
There have been some problems with Micro Softs Macro Assembler:
Screens do not get cleared between charts, and the colors sometimes get
changed a little, especially bright yellow. But once Quit is chosen from
CREFR everything gets back to normal, so while its a little messy, it WILL
work with the Macro Assembler.
I hope you find this TSR version of CREF as useful as I have, as always, if
you have a comment or suggestion, please let me know. You can use the
Comments form provided. If there is something you would like to see added to
the CREF program...tell me, I'll probably do it!
Thanks...Rand Nowell
