 Dummy; Keep the A/**<n> format for reading by JGConfig. This documents the Code
 and Size parameters of the configuration files, whose settings adapt JGPrint to
 the user's printer and the default layouts she requires.

A\|
**-4

   Sizes are single non-negative integer values as opposed to Codes which are
strings of byte-size values, i.e. between 0 and 255.

   The Size parameters determine various aspects of JGPrint's operation.  They
are held as non-negative integers, and, mostly, express measurements.
Horunit, whose value gives the fraction of an inch that is the unit for the
printer's minimum horizontal motion, is an example of this kind of Size
parameter.

   Many size parameters give the default initialisations for the page layout,
and these have names beginning with 'init'

   The second main class of Size parameters are truth values: 0 is interpreted
as false; any positive number as true. JGCnfig displays F as a synonym for 0
and T as a synonym for 1. It will also accept these letters, and their lower
case equivalents as input for these values. DoFF, which determines whether or
not JGPrint emits a formfeed(12) between pages with continuous feed is an
example of this kind.

   A small class of size parameters express bytes for #(hash), £(Pound) etc.
The size parameters for initialising the fill and justify style are  purely
conventional codes, detailed under Initfj:

   Some Sizing parameters get round operating system bugs; Drive is an
example.

   Some sizing parameters use an ad-hoc code. Initfj(qv.) is an example.

A\|
**-3

The Names under which the codes and sizes are manipulated in JGCnfig are
intended to have a connotative meaning for the user. JGPrint itself knows
nothing about these. The user has the option to alter them if what is
connotative to me is not connotative to her.

However, the documentation is in terms of the names I have chosen, and, also,
there is a restriction on the total number of characters that can be used. I
suggest  that you do not change them without very good reason.

Codes are strings of byte-values, each between 0 and 255 in value, as opposed to
Sizes, which are single non-negative integers.

Codes usually specify a printer directive, with '%'+<l> specifying the
appropriate inclusion of a parameter. (see MOVE/CODE/DIRECTV for details.)

If the size Esc is true, all codestrings are preceded by escape(27>, with the
exception of Rc(85) - Horbyte(92) (qv.)

More codes are specified than JGPrint presently makes use of. This not only
provides upward compatibility for JGPrint"s future development, but also may
help to standardise if \\. etc. are used. V0-V9 are provided for the user to
rename for facilities I have not foreseen.

Printer determines the recognition string used in JGPrint and JGCnfig to
enable the user to recognise that the intended configuration file has been
provided; Propchwidth names the associated q font file. Source enables the
supplier of a configuration file to take responsibility for it.

An empty string is known as 'Null' if it is to be ignored, 'Forbidden' if its
occurrence when JGPrinting should provoke a diagnostic.

A\|
**21

21. Pitch: Code put out by JGPrint with parameter if Pitch is non-Null,
superseded by Cpi10 etc. Intended for printers with variable pitch. Usually Null
with dot-matrix printers.

A\|
**22

22. Lm: Left margin code. If Null, JGPrint will put out spacing as best it can
to effect the required left margin specified by <l> in .cpi <c> <l> <m>. It is
increasingly my practice to put lm Null to improve registration at a slight
speedcost.

A\|
**23

23. Rm: Right margin code. Not used by JGPrint.

A\|
**24

24. Spacing: The code put out to determine line separation as a result of the
..sp <n> directive; the size parameter Vertunits converts the value given in
the .sp directive to that required by the printer mechanism. If Spacing is
Null, the printer is taken to have fixed line separation, and .sp in the body
of the text will produce a diagnostic complaint. (cf. Initsp 6/134).

A\|
**25

25. Point: Code to specify height of characters. If non-Null any cpi <n> command
generates a Point <m> printer code where <m> = 72/<n> (rounded down).

A\|
**26

26. Uln: Code to start underlining. JGPrint emits this code as required by the
\\U, \\X and \\Z directives. If Uln0 is Null, this code is issued to precede
every character to be underlined, rather than expecting Uln0 to cancel
underlining.

A\|
**27

27. Uln0: Code to cancel underlining. If Null, JGPrint precedes every character
to be underlined with Uln.

40. Qual: code to enter quiet mode issued as a result of the directive \\Y;
alternatively used for draft printing.

A\|

41. Qual0: code to cancel quiet mode issued as a result of the directive \\Z;
alternatively used for letter-quality printing.

42. Incr: code to enter incremental mode issued as a result of the directive
\\K. In some configuration files this is, alternatively, used for High Speed
Draft.

A\|

44.  Bidir: code to initiate twoway printing issued as a result of the
directive \\N.

A\|

45. Unidir: code to initiate oneway printing issued as a result of the
directive \\O.

47. Subscpt: code to initiate Subscript printing issued as a result of the
directive \\S.

A\|
**48

48. Supoff: code to cancel Superscript printing issued as a result of the
directive \\T.

A\|
**49

49. Suboff: code to cancel Subscript printing issued as a result of the
directive \\T.

A\|
**50

50. Chram: code to select secondary characters issued as a result of the
directives \\x and \\y. These may be those defined in RAM or a secondary set
defined to be available in Init.

A\|
**51

51. Chrom: code to select ROM characters issued as a result of the directives
\\y and \\z. They are the primary set defined to be available in Init.

A\|
**52

52. Hln: code to perform a half-depth linefeed, used, by preference, as a
result of the directive .hln; if Null, Downtab(54) with a parameter of half
the current spacing is used instead.

A\|
**53

53. Uptab: code to execute a reverse vertical tab. Based on Vertunit, JGPrint
provides it with the correct parameter. Initup and //< cause its use. (cf. Vmax
177/49).

A\|
**54

54. Downtab: code to execute a forward vertical tab. Based on Vertunit, JGPrint
provides it with the correct parameter. JGPrint uses it for .fig, and to
adjust the vertical position of the printhead when spacing is not an exact
divisor of page length. (cf. Vmax 177/49).

A\|
**55

55. Vmi: Code for general vertical motion used with positive and negative
parameters. If non-Null, it is used in preference to Downtab(54) and
Uptab(55).

A\|
**56

56.  Hmi: Code for general horizontal motion.  It may be that the printer can
only execute forward motion.  JGPrint introduces forward motion only when
justifying with FGFJ and JGFJ. \\}-<n> and \\{<n> cause commands for backward
motion to be issued. Printers differ most, in my experience, in how they
handle horizontal motion. See MOVE and CODE to examine the range of
possibilities that JGPrint can presently cope with.

A\|
**57

57. Cr: code which, if non-Null, is issued in place of byte 13 to cause a
carriage return; Some VDUs are non-standard in this respect.

A\|
58. Hue: Code to change the colour being used for printing issued as a result
of the directive \\H<n>.

directive .land.

A\|
**64

64.  Port: Code to return to Portrait printing, issued as a result of the
directive .port.

A\|
**65

65.  SFeed: Code to cause Sheet Feed issued at page breaks. For continuous
stationery it should be Null.

70. Symbols: Code to cause certain bytes to be interpreted as synbols; not
used explicitly by JGPrint.

A\|
**71. Tochars: Code to cause control bytes to be interpreted as printed
characters, issued by JGPrint at the beginning of each line. \\!<n> provides.


A\|
**72

72. Toctrl: Code to re-enable bytes as control characters, issued by JGPrint at
the end of each line.

A\|
**73. Tochar1: Code to treat the following byte as a character rather than as a
control code when it occurs in a line of text.

A\|
**74
74. 9char: code to interpret byte 9 as a character rather than a tab when it
occurs in the middle of a line. (Obsolescent)

A\|
**75

75.  27char: code to interpret byte 27 as a character rather than as an
escape to a control command when it occurs in the middle of a line.

76. Horpos: code to set the horizontal position of the print head; not used
explicitly by JGPrint.

A\|
**77

77. Vertpos: code to set the Vertical position of the print head; not used
explicitly by JGPrint.

A\|
**78

78. Pushpos: code to stack the current position of the print head; not used
explicitly by JGPrint.

A\|
**79

79. Poppos: code to unstack the former position of the print head; not used
explicitly by JGPrint.

A\|
**80

80. Pathor: Code to set a horizontal pattern for filling; not used explicitly
by JGPrint.

A\|

81. Patver: Code to set a vertical pattern for filling; not used explicitly by
JGPrint.

preceded by escape(27).

A\|

86.  Uc: code to move the screen cursor up one line.  Not automatically
preceded by escape(27).

87.  Dc: code to move the screen cursor left, deleting the preceeding
character.  Not automatically preceded by escape(27).

A\|
**88

88. Source: a string to hold the signature of the originator of a
configuration file. My practice is to put my initials, jl, followed by date
and year.

A\|
**89

89. Romtoram: code to transfer the Rom characters to Ram. Beware, changing
cpi, ps, etc. may wipe the store. I have been very puzzled by a print run that
only showed where characters were to be underlined.

The current code used by JGPCPCopy is [<esc>}0(Null); The 0 is followed by the
current page number as a numeral.

A\|
**98

98.  Abshor: If this command is non-Null, all ink characters can be preceded by
this command with an appropriate parameter to position the print\-head in the
correct absolute horizontal position on the line. In particular, italic and bold
characters may be forced to the same or proportionally wider width as the
corresponding non\-bold, non\-italic characters. The use of abshor is controlled
by the size parameter abshorP, and the size parameters Ital0/1, Bold0/1.

Setting the command abshor 'Forbidden' is forbidden.

A\|
**99

99   Lpispacing: Code for linespacing in lines per inch. If Null, sp 1-10 is
calculated using vertunits and the code Spacing. This may lead to rounding
errors downwards.

A\|
**100

100   Paperform: Set Paperformat code for printer. This is done if the size
parameter Paperform is set non-zero on entry to JGPrint before the init code, or
if \\^<n> is encountered. The parameter <n> is printer dependent.

A\|
**101

101. Feedfrom: Feeds a new sheet of paper from the required printer tray
etc. If the Size parameter Feedfrom is non\-zero this is done on entry to
JGPrint before the init code, or if \\%<n> is encountered. The parameter <n> and
the precise effect are printer dependent.

A\|

11" is 23740; A4 is 25200. (cf.Skiplines/Skiplength/Skipsingle (148-50/20-2).)

A\|
**134

134/6. Initsp: The default initialisation of spacing between lines. If <= 10,
to be construed as lines per inch; if <= 120, as lines per page, otherwise as
vertical units. (cf. spacing(24), and Splpp (41/169)).

mechanism (cf. initSS (188/60)). The effective pagelength is Initpl(133/5) minus
Skipsingle unless a .pl <n> command is encountered in which case it is <n> minus
Skipsingle. Of course, Pl might be given in inches in either case, and you
should multiply by 2160 if so.

166/38. Pagecycle: Frequency with which printer halts at page-break to allow
paper reset; 0 is construed as never.

A\|
**167

167/39. Ftpgrestart: True to restart footnote numbering on successive pages,
false for incrementation across pages.

A\|
**168

168/40. Romchar: Extra character to put in to prevent alternative ROMs
accepting a command; obsolescent.

A\|
**169

169/41. Splpp: true implies that argument of the command spacing(24) is always
based on lines per page.

A\|
**170

170/42. mc.pound: byte produced by the pound(£) key on the machine on which
texts are prepared.

A\|
**171

171/43. Rightdown: True if positive arguments to Hmi and Vmi move the paper to
the right and downwards; false if to the right and upwards.

A\|
**172

172/44. 17p: Font used by proportionally spaced characters at cpi8.5 and
cpi17.

A\|

173/45. 12p: Font used by proportionally spaced characters at cpi12 and cpi6.

A\|

180/52. VFeedunit. Number of units to the inch of the code used to set the
vertical spacing between lines. If Zero, use Vertunits.

A\|
**181

181/53. AbshorP. Controls the use of the absolute horizontal position rather than
relative position code. Values:
.nofj
        0           Use spaces and relative code;
        1           Omit spaces and put out absolute code before any ink
                    character string;
        2           Omit spaces and put out absolute code before any ink
                    character.
.fj
(cf. Ital0/1 (158-9/30-1) and Bold0/1 (190-1/62-3).\|
1 and 2 require the code abshor to be available. 2 can be slow; 1 is probably
the fastest.\|
2 enables type to be squeezed or expanded using proportional spacing character
widths of your choice rather than those of the actual font. If you are not sure
you have correctly specified the width of characters to JGPrint, 2 may be
helpful.

182/54. Drive. Drive on which JGPrint is mounted. Normally ignored, but this
is an area in which operating systems sometines fail to act as documented, in
which case this value is consulted. The various 6502 emulations on the
Archimedes suffer from a bug here. Obsolescent.

A\|
**183

183/55. Slow. Delay exacted between output of each line on the screen. Only
implemented on MSDOS and native Archimedes. The unit is 1/100 seconds, and I
find 60 suits me.

A\|
**184

184/56. Mc.pound2. A second byte that will be construed as the Pound sign when
printing. A value of 0 will be ignored.

This is particularly valuable when files for JGPrinting are being written on a
second machine.

A\|
**185

185/57. Vup. Set true if the printer is required to roll back when reloading
paper for verso printing.

A\|

186/58 Paperform: Initialising value for the code paperform(101).

A\|
**187

187/59 Feedfrom: Initialising value for the code feedfrom(102).

A\|
**188

188/60: InitSS: Controls default assumptions about the paper feed
arrangements. The codes:
.nofj
        0           Continuous paper: vertical space not used on one page
                    carried over to next; Skiplines and Skiplength used to
                    modify pagelength; only if sfeed code non\-Null is any
                    interpage code emitted.

        1           Sheet-feeder or hand\-fed paper; unused vertical space
                    NOT carried over; Skipsingle modifies pagelength; doFF
                    or sfeed interpage code; no pause between pages.

        2           As 1 but prompts between pages.
.usel base

The user may choose whether or not to use this code to set the paper source,
according to what best fits her printer.

Sheet feeders probably work best if the assumed printable pagelength (cf.
Skipsingle(150/22)) is set to somewhere less than the actual printable
pagelength, and a form feed is used to finally eject each page (cf.
SSdoFF(179/51)).

The carry\-over of unused vertical space is potentially needed if the
actual space used by the lines on one page does not fill up the space
specified by Initpl/.pl, and the printer mechanism cannot vertically tab
over the surplus.

189/61. CrandLn: If true put out a cariage return before a newline.

A\|
**190

190/62. Bold0: Value in horunits, i.e. dots, of extra width to be added
algorithmically to the assumed width (escapement) of proportionally widthed
characters. NB. HP uses <n> in font specification to specify a value of <n>+1;
Epson seems to squash their characters to achieve a value of 0.

**191

191/63  Bold1: Coded value to find width of Bold characters in font 1.
For details see Bold0.
