[SET] PAGEWRAP ON|OFF

The SET PAGEWRAP command allows the user to turn on or off the
automatic wrapping of <FORWARD> and <BACKWARD> commands when the cursor
is at the <Bottom-of-File line> or <Top-of-File line> respectively.

COMMAND
set parser - associates a language definition file with a parser
SYNTAX
[SET] PARSER parser file
DESCRIPTION
The SET PARSER defines a new syntax highlighting <parser>; 'parser' based
on a language definition file; 'file'.
The 'file' is looked for in the directories specified by <SET MACROPATH>.
To specify one of the builtin parsers, prefix the filename with '*'.
Therefore to define a <parser> called FRED using the builtin C parser,
the command would be: SET PARSER FRED *C.TLD.

COMMAND
set pending - set status of pending prefix commands
SYNTAX
[SET] PENDing ON string
[SET] PENDing OFF
[SET] PENDing BLOCK string
DESCRIPTION
The SET PENDING command allows the user to insert or remove commands
from the pending prefix list.
ON string, simulates the user typing 'string' in the <prefix area>
of the <focus line>.
OFF, removes any pending prefix command from the focus line.
BLOCK string, simulates the user typing 'string' in the PREFIX
area of the focus line and identifies the prefix command to be
a BLOCK command.

COMMAND
set point - assign a name to the current line
SYNTAX
[SET] Point .name [OFF]
DESCRIPTION
The SET POINT command assigns the specified name to the
<focus line>, or removes the name from the line with the specified
name.
A valid line name must start with a '.' followed by alphanumeric
characters. e.g. .a .fred and .3AB are valid names.
When a line is moved within the same file, its line name stays
with the line.

Does not allow for multiple names for the same line.

set prefix - set prefix area attributes
SYNTAX
[SET] PREfix ON [Left|Right] [n [m]]
[SET] PREfix Nulls [Left|Right] [n [m]]
[SET] PREfix OFF
[SET] PREfix Synonym newname oldname
DESCRIPTION
The first form of the SET PREFIX command allows the user to display
the <prefix area> and optionally to select the position were the
prefix should be displayed.
The second form of the SET PREFIX command is functionally the same
as the first form. The difference is that when the prefix area
is displayed with <SET NUMBER> ON, numbers are displayed with leading
spaces rather than zeros; with <SET NUMBER> OFF, blanks are displayed
instead of equal signs.
The third form, turns the display of the prefix area off.
Executed from within the profile, the only effect is that the
defaults for all files is changed.
Executed from the command line, the SET PREFIX command changes the
current window displays to reflect the required options.
The fourth form of the SET PREFIX command allows the user to specify
a synonym for a prefix command or Rexx prefix macro. The 'newname'
is the command entered in the prefix area and 'oldname' corresponds
to an existing prefix command or a Rexx macro file in the MACROPATH
ending in .the or whatever the value of <SET MACROEXT> is at the time the
prefix command is executed. The 'oldname' can also be the fully
qualified filename of a Rexx macro.
To turn off a prefix synonym, call SET PREFIX newname oldname where
'newname' and 'oldname' are the same and 'newname' is an existing prefix
command or macro.
The first and second forms of the SET PREFIX command allows the user
to specify the width of the prefix area and optionally a gap between
the prefix area and the filearea.
'm' can be specified as an unsigned number between 2 and 20 inclusive.
'n' can be specified as an unsigned number between 0 and 18, but less
than the number specified in 'm'.

Specification of prefix width ang gap is a THE-only option. Kedit has

COMMAND
set printer - define printer spooler name
SYNTAX
[SET] PRINTER spooler|[OPTION options]
DESCRIPTION
The SET PRINTER command sets up the print spooler name to determine
where output from the <PRINT> command goes.
The 'options' can be one of the following:
CPI n (characters per inch)
LPI n (lines per inch)
ORIENTation Portrait|Landscape
FONT fontname (name of fixed width font)
No checking is done for printer options. i.e. You may specify a
font that THE doesn't know about, and the printing process may
not work after that.
The defaults for page layout for Win32 are:
CPI 16
LPI 8
ORIENTation Portrait
FONT LinePrinter BM
'options' are only valid for Win32 platform.
Printer output for the Win32 platform ALWAYS goes to the default
printer. Therefore, the 'spooler' option is invalid on this
platform.
