and watch the program scroll down the screen. Freeze the

scrolling by pressing down on the Commodore key so you can

read the statements. Then, resume scrolling by touching any

key.

I am submitting a file named "finalgrafxtables" to the CBUG

library. This file is a replacement for "grafx maketables", which

should be discarded. It will contain all the corrections to "ss2

maketables" which have been described in this series of reports.

Remember, you only have to make these changes once—the

program will create a file "ss2 tables" on your disk, which you

can use over and over, every time you load SuperScript—so give

it a try! You too can have graphics today!

Still doubtful? I am also submitting a sequential file created

in SuperScript, named "4023graphicsdemo". Load this file into

SuperScript, then output it to the printer. It will print the graph

you saw when you ran the "printer demo" on the 8050 demo

disk. Study the screen, comparing it with the printed graph,

until you understand all the ins and outs of switching back and

forth between graphics mode and lower-case, enhanced and

reverse printing, and overprinting on the same line.

Vertical graphs are just as easy to create! Here’s how I made

the quarterback salaries portion of that file. I defined the row

of graphics for the chart at the top, then used the ESC A (append)

command to copy it several times, as explained in the super

script tutorial on page 25. Finally, I cut off the tops of the

columns, each in turn, by defining a row of blanks and doing a

column move down until each column was the desired height.

The command *sa6,21 tightens up the printer’s line spacing so

that the graphics will connect. It’s used at the end of the second

line before you want it to go into effect. *sa6,36 will get you

back to th^ normal 6 lines per inch. Thus text alongside the

chart should be double spaced. As you can see, the 4023 is not

too precise about lining up the vertical lines, so some graphics

will be more suitable for this application than others. Have fun

decorating your documents with fancy output like this, courtesy

of Superscript II. Editors Note 2 articles were combined.

SUPERBASE TIP by Bruce Faierson

If printer commands are sent to an ascii printer in Superbase,

the codes themselves are also converted. To avoid this problem,

send a converted code or use pdef 0 before sending the codes

and reset the printer with the correct pdef setting afterwords.

4023 - 8023P PRINTER ROMS_by Dave Ritterbusch

This article describes the changes/additions I have made to

the 4023 & 8023P printer ROMs which make the printers

compatible with the B-128 keyboard. For example when you

type a left bracket the printer also prints the left bracket and not

the graphics character. There are a total of 19 corrections to the

8023P ROM and 20 corrections to the 4023 ROM. The extra

correction to the 4023 ROM is the small (k) which is changed

to NOT look like a capital (K). These changes will also facilitate

some graphics on Superscript III.

A good place to start this description is with reference to the

Silver/Blue manual ’B SERIES - COMMODORE USERS

GUIDE’ that came with the B-128. Appendix D pages 116 &

117 is a list of the B-128 Chr$ codes and characters. The notes

at the bottom of page 117 of the manual should read as follows:

GRAPHICS MODE:

CODES 96 -127 are the same as 3 2-6 3

CODES 224 - 253 are the same as 160 -190

CODE 255 is the same as 222

CODE 254 is the programmable character.

NORMAL MODE:

CODES 96 - 127 are the same as 160 - 190

CODES 224 - 253 are the same as 32 - 61

CODE 255 is the same as 222

CODE 254 is the programmable character.

The following is a list of characters that have been changed

to match the keyboard in both the NORMal and GRAPHies

modes.

CHR$#

MODE ACTION

chr$ 91 normal

changed to left bracket

chr$ 91 graphics

added degree symbol

chr$ 92

both

changed to UK pound sign

chr$ 93 normal

changed to right bracket

chr$ 93 graphics

added combined + /- sign

chr$ 94

normal

changed to up arrow

chr$ 95 normal

changed to back arrow

chr$ 167 normal

changed to right vert, bar

chr$ 170 both

changed right vertical bar

chr$ 180 both

changed left vertical bar

chr$ 181 both

changed left vertical bar

chr$ 182 both changed right vartical bar

chr$ 183 graphics

changed upper horizontal bar

chr$ 184 graphics

changed lower horizontal bar

chr$ 219

normal

added degree symbol

chr$ 220 normal changed to UK pound sign

chr$ 221 normal added combined + /- sign

chr$ 222

both

redesigned PI symbol

chr$ 223 normal changed graphic character

What does all of this mean? It means you do NOT have to

use a special utility to be able to print brackets. Also, when you

receive data from a network such as DELPHI or COM

PUSERVE the information you see on the screen is what the

printer will print. The two added characters, the degree symbol

and the combined + /- sign can be printed using a command

PRINT CHR$(219) or PRINT CHR$(221) respectively with the

printer in the UPPER/LOWER case mode. These can easily be

printed from Superscript III using the FEATURE feature when

the printer DEFAULT file is set up to use this capability.

The printer ROM exchange is very simple for both of the

printers. It requires no special tools. You need only remove the

cover/lid, unplug the old ROM, plug in the new ROM and

replace the cover/lid. The instructions supplied with the ROM

explain the procedure in detail with photos of how to perform

the printer ROM exchange.

The B-128 character ROM has a couple of errors which I

have also corrected. This ROM is not so easy to replace since it

must be unsoldered from the main board. The ROM changes

reverse the GRAPHics characters on the C & V keys. I also

changed the shape of the capital (O).

interest, Dave may offer the roms again!!!
