Then list line 3050 with this command:

list 3050 (return)

It should appear as follows; 3050 data 0,0 Change the screen

to read

3050 data 0,145

and again push (return) while the cursor is still on that line.

Now, run the program in memory with this command:

run (return)

(type in the word "run"—do not use the (run key). What will

happen is that the program will create a file on the disk you put

in drive 1 earlier, named "ss2 tables". You might want to check

the directory on drive 1 first to be sure you don’t already have

a file with that name there; if so it will be erased. This is a

binary-type program file, not a BASIC program. The steps

detailed above will only have to be done once, unless you

subsequently erase the "ss2 tables" file.

Whenever you want to use the second method of generating

graphics, you must have a disk in drive 1 with this "ss2 tables"

program on it, and the SuperScript disk in drive 0 as usual. But

do not use the usual method of loading SuperScript! (Do not

press SHIFT/RUN.) Enter this command:

dload"ss2" (return)

When the "ready" message appears and the cursor returns,

enter this command:

run (return)

(The BASIC program "ss2" already exists on the SuperScript

disk.) When the start-up menu appears, choose "0. CBM

Matrix Printers" as usual. Now refer to the SuperScript manual,

page 129. The sequences ESC ; and ESC which are listed as

not applicable in the CBM Matrix column, are now available for

you to use at any time. Recall that SuperScript will supply a

cursor-down at the beginning of each line. Any time that you

want graphics to appear on a printed line, just key in ESC (using

the escape key) and all subsequent characters on that same line

will be printed out in graphics/upper case mode. That is,

characters which are lower case on the screen will be upper case

on the printer; and characters which are upper case on the screen

will be graphics on the printer. To switch back to lower case

again on the same line, just key in ESC ; which will show up

on the screen as a graphic (ESC > will also show as a graphic).

You can switch back and forth on the same line as many times

as you like, but remember that each new line will start out in

lower case.

A word of caution: Some of the control keys will print

graphics on the screen, but these will not be output on the printer.

Instead, they will activate special printer functions such as

enhanced printing (double width). This is true for both methods

of generating graphics. Be sure to experiment with the graphics

you want to use before trying to create an important document

with it. A report is being prepared for the fall issue outlining

further changes in the "ss2 maketables" program that should

eliminate this problem.

A further enhancement to the program used to set up the

second method will allow access to the ESC ’ function. If line

3030 is changed to read

3030 data 17,0,141

instead of 3030 data 17,0,0 then the escape apostrophe

sequence can be used to send a carriage return without a line

feed to the printer. This capability could be useful in overprint

ing graphics on the same line, or in underlining. It is necessary

to change the right margin at the end of the preceding line

(double it) unless the line containing the text to be underlined

or overprinted is very short, because a line-feed will be forced

when the count of characters before and after the escape se

quence combined, reaches the right margin number (usually 80).

Then reset the right margin.

GRAPHICS UPDATE & FINALE hy Neil Ctimfer

An earlier report outlines with great detail the procedure

to be used in setting up enhanced graphics capabilities. A few

graphics were still unprintable, in particular those shown on

these keys: 2, 6, 8, 0, C, and the keypad’s /. This report

explains changes that will allow even these graphics to be printed

out.

Load "ss2 maketables" from the SuperScript disk and make

these changes to the program in memory:

Delete lines 2810-2920, replacing them with this line:

2810 data 210,128,128,215,140,128,159,146,128,149,

206, 128

Change line 3030 to read: 3030 data 17, 0, 141

Change line 3050 to read: 3050 data 0, 145

Change line 3140 to read: 3140 data 172,192,162,93,164,

165, 167, 95, 187, 175

Then run the program with a disk (not the SuperScript disk!)

in drive 1. If you prefer, the CBUG library can supply a disk

with the program "grafx maketables", in which these changes

have already been made, as well as the version of "ss2 tables"

which is created by it.

As before, to use graphics you cannot load SuperScript in

the normal way. With SuperScript in drive 0 and "ss2 tables"

in drive 1, dload "ss2",d0 and run. If you use Pre-SuperScript,

hyperdrive, your own logo, and/or other preparatory routines,

you must incorporate these two files in the sequence. One way

is to change the line which loads "superscript*" or"superscript

II" to ss2".

Here’s a summary of the changes the current program will

have on SuperScript when the "CBM Dot Matrix Printer" option

is chosen.

Keystroke Screen Effect on

Sequence graphic 4023 printer

ESC $ reverse $ prints the British Pound sign

ESC ( reverse R prepares printer for reverse

field printing

ESC ) reverse r cancels reverse-field printing

ESC [ reverse W prepares printer for enhanced

printing (W = wide)

ESC ] reverse N cancels enhanced printing

(N=narrow)

ESC ’ rev 1-arrow forces a carriage return on the

printer without a line feed

ESC > reverse u puts printer in temporary Upper

case & graphics
