- Documentation for BIGECHO
-
- What it does
-
- BIGECHO is a stand alone program which you can use at the DOS
- command line and, more often, in BATch files. To see what it can
- do, run one of the two sample BATch files included in the package.
- If you have an ANSI compatible screen driver installed (eg
- ANSI.SYS, NANSI.SYS, FANSI-CONSOLE or TALL SCREEN) and a color
- (CGA or EGA) monitor installed, run ANSIDEMO.BAT; if not, run
- BIGDEMO.BAT. These files use the public domain program WAITN by
- Ken Goosens which we have borrowed and the ANSIDEMO file uses SEND
- by Howard Rumsey and Barry Simon.
-
- BIGECHO will display a message in characters 8 lines high and 8
- wide. The usage is
- BIGECHO <message>[/FB]
- The message can be up to 10 characters in length and can contain
- any character with ASCII code 127 or less except for the slash
- (ASCII 92). Any characters after the tenth are ignored and spaces
- after the one required by DOS count so if you want to center
- "hello!", place three blank spaces after the BIGECHO. Some of the
- control characters have interesting patterns, especially the happy
- faces, ^A and ^B.
-
- The /FB is optional. If it is not included the default is to have
- F=█ and B= <space> so that the filled in parts (Foreground) of the
- character are replaced with the solid block and the empty parts
- (Background) by the blank space. In general, F and B can be any
- ASCII characters. WARNING: if you put in / with no parameters and
- two or more spaces, BIGECHO interprets that as F and B being
- spaces and will display blank lines. Placing / without the spaces
- will cause even more undesirable behavior.
-
- Interesting combinations for /FB include ASCII 219,197 (/█┼) and
- ASCII 206,176 (/╬░). The ASCII table in CTRLALT is ideal for
- looking at and entering higher ASCII combinations.
-
- The file BIGECHO.SPL contains samples of the output for various
- sample command lines.
-
- BIGECHO sends its output to standard output and it can be
- redirected BUT the result will probably not be what you want! DOS
- automatically wraps screen writes after 80 characters so the 640
- characters produced by BIGECHO come in a stream without CR/LF
- pairs. Thus most printers will not display things properly and
- redirection to a file will not display properly either. The
- sample file was produced by redirecting output and putting the
- CR/LF in by hand with a word processor.

- GOODDAY
-
- GOODDAY is a standalone program using the same technology as
- BIGECHO which responds depending on the time of day and on whether
- it's Friday. Novices seem to like it run as the last program in
- their autoexec.bat. And don't tell us that it's hardly evening at
- 11:30 pm or night at 5:55 am. We know but GOODDAY insists.
-
-
- How it works
-
- The monochrome adapter comes with its own character ROM, that is
- built in programming telling the display the dot pattern to use
- for each character but the CGA does not and the dot pattern must be
- contained in ROM on the computer itself. Thus every IBM
- compatible computer must have 8 by 8 dot patterns for each
- character stored in its read only memory and it is this pattern
- that BIGECHO accesses. Those dots in the pattern that are
- "foreground" to the adapter are replaced by character F and those
- that are background are replaced by character B. If you don't
- like the pattern for some letter, don't complain to us as we
- didn't pick them; complain to your computer maker!

- A Bow and Two Disclaimers
-
- BIGECHO was developed by Barry Simon and Richard Wilson.
- GOODDAY is c(o) by Wilson. It is POSTWARE: if you like it, send
- a postcard addressed to us at
- 253-37 Caltech
- Pasadena, CA 91125
- Of course, we're glad to hear comments, suggestions about
- enhancements, and even about complaints, incompatibilities and
- bugs. Simon has a Compuserve number [76505,2315] . You can leave
- messages via EMAIL or, preferably, at the IBMSW Sig. Suggestions
- for enhancements would be especially welcome since we already have
- some ourselves and plan a second version some time or other. You
- can find the version of BIGECHO by using the DOS command "type
- BIGECHO.COM". And if you like the program please give it to your
- friends, place it on bulletin boards and otherwise spread it
- around. While it is copyright by the two of us, we explicitly
- allow use of it privately and in a commercial environment. You
- may give it away but you may not charge for it or include it with
- commercial software without our permission. An exception is made
- for user groups and public domain software distributors who may
- include it on a disk so long as a reasonable fee is levied.
-
- While we have a connection with Caltech, we emphasize that
- this program has no such connection.
-
- And we make the usual disclaimer: this software is
- distributed "as is" and is warranted for no purpose. Any risk
- associated with its use including, but not limited to, loss of
- data is borne by the user.
