MODCOM 1.0
by

COPYRIGHT 1992
═══════════════════════════════════════════════════════════════════════════
MODCOM is an offshoot of another program called DBPRG which is a CLIPPER
program editor. MODCOM has been specifically designed to be used as the
COMMAND EDITOR within DBASE III+. It does not have all of the features
of DBPRG because it was designed to maximize the available memory.
Also I have eliminated all of the LIBRARY function calls which I included
in DBPRG for the obvious reason that these function calls are useless in
a DBASE III program. Further, I attempted to get rid of all the CLIPPER
specific Commands from the Command database. I believe I got them all but
if I failed to delete one or two just ignore them.
What is left after all of this elimination is still quite a powerful
Command editor. I hope that it is useful to you.
═════════════════════════════INSTALLATION══════════════════════════════════
To install MODCOM do the following:
1. Make a directory off of your root directory called \MODCOM and place it
in the PATH statement in your AUTOEXEC.BAT file. (This is important
because MODCOM looks for it's data files in this directory... it writes
PRG's wherever it happens to be called from thus you may call MODCOM
from any directory and it will function properly).
2. Copy MODCOM.ZIP into that directory and UNZIP it there.
3. REBOOT to establish the PATH
4. In your config.db file (if you don't have one of these you should make
one...see DBASE III+ manual)...place the statement TEDIT=MODCOM
and MODCOM will be called whenever you issue the command MODIFY COMMAND
from within DBASE III+.
(USER FRIENDLY TIP) -- You may want to append the following feature
discussion to the end of the file called hlp.prg while you are learning
the commands. That way if you have a question you can hit F1 and page
down to reveal that text. It uses memory or I would have done that
for you.
══════════════════════════════FEATURES═════════════════════════════════════
KEY FUNCTION ACTION
═══════════════════════════════════════════════════════════════════════════
F1 HELP Help screen
F2 COMMAND MACROS Pressing F2 within the editor causes a popup
list of commands to appear. This list responds
to the first KEY protocol. If you press 'D'
the first selection starting with D will come
to the top of the screen. Pressing Enter will
cause the Command (together with its syntax to
be transferred to your program starting at the
cursor. You can then "fill in the blanks" with
the syntax or just delete it.
F3 FUNCTION MACROS Pressing F3 within the editor causes a popup
list of functions to appear. This list responds
to the first KEY protocol. If you press 'D'
the first selection starting with D will come
to the top of the screen. Pressing Enter will
cause the Function (together with its syntax to
be transferred to your program starting at the
cursor. You can then "fill in the blanks" with
the syntax or just delete it.
F4 VARIABLE ENTER Pressing F4 will cause a single entry screen to
pop up over the screen. You may enter a Variable
of up to 15 characters. When you press enter
The Variable will be transferred to your program
starting at the cursor. The Variable is also
stored in a database of up to 100 variables for
later recall using F5.
F5 VARIABLE SELECT Pressing F5 pops up a selectable list of
Variables which you have previously entered
using F4. Use the arrow keys or Page Up and
down to find the variable name and then press
ENTER to transfer the Variable to your program.
ALT-F5 VARIABLE LIST Pops up the Variable list but does not copy it
to your program when you exit.
CTRL-F5 DELETE VARIABLE Pops up the list of variables from which you
may select one to delete.
F6 IMPORT PROGRAM Pops up a list of available PROGRAM FILES in the
current directory which you may select from.
Pressing ENTER will cause the contents of the
selected file to be imported to the program
starting at the cursor. (see warning below)
F7 ASSIST Once you have entered a COMMAND or FUNCTION
using F2 or F3 pressing F7 will pop up a syntax
help screen to help you remember what all those
"exp2" and "Nexp3" etc etc mean.
F8 COPY BLOCK TO MEM After using ALT-M to mark the beginning and end
of a block. Use F8 to copy it to memory. Then
use ALT-P to paste it.
ALT-F8 COPY BLOCK TO FILE After using ALT-M to mark the beginning and end
of a block. Use ALT-F8 to copy the block to a
file.
F9 CHR() ENTER Pressing F9 will cause the next character you
enter to be converted to the form "CHR(NUM)".
If you hold down the ALT KEY and enter numbers
from the KEYPAD the numbers will appear inside
the CHR( ) parenthesis. By the way if you
don't press ALT-9 first holding down the
ALT KEY will cause the non-keyboard character
to be written to your program.
example: Holding ALT down and pressing 1 7 7
will cause '▒'.
Hitting F9 then ALT+1+7+7 will result in
CHR(177). HITTING F9 and then ALT+F2 will give
you CHR(-31)
F10 SAVE/EXIT Same thing as hitting CTRL-W.
ALT-S SAVE Saves the program to the data base and returns to
the edit screen.
ALT-M Mark a block -you need two marks to make a block
ALT-P After saving a marked block to memory use Alt-P
to paste it into the text.
ALT-F
or Enter a line number to go to.
ALT-L
═════════════════════WARNING═══WARNING══WARNING════════════════════════════
Using F6 to import a program file will cause all the semi-colons to be
transformed into line feeds. So if you use a lot of semi-colons don't
use F6. Thus if you use
x='this is a very long line which I will break here'; <-(semi-colon)
'and continue here so that I can read it all'
an attempt to IMPORT using F6 it will come out like this
x='this is a very long line which I will break here' <-(linefeed)
'and continue here so that I can read it all'
and crash your program. There is a fix for this but you will have to
register the program to get it.
