1.
@NEW PARAMETER .INVO (OUTPUT CASE INVERT) DISTINCT FROM
.INVERT, WHICH NOW APPLIES ONLY TO INPUT. @THIS PERMITS
PROPER TREATMENT OF THE SITUATION WHERE DIFFERENT CASE
CONVENTIONS ARE REQUIRED IN THE INPUT AND UPDATED OUTPUT.
@THE DEFAULT SETTINGS ASSUME UPPER-CASE LETTERS PLUS CASE
MARKERS, WITH THE LETTERS SIGNIFYING LOWER-CASE UNLESS
GOVERNED BY A MARKER. @NORMAL UPPER AND LOWER-CASE REPRESENTATION
IS ACHIEVED BY .$$A$ CAP=0;$ CAPSH=0;$ INVERT=0 (FOR INPUT)
AND .$$A$ CAPO=0;$ CAPSHO=0;$ INVO=0 (FOR OUTPUT).

$$@L0 IS INTERPRETED AS INTRODUCING AN INDEFINITE NUMBER OF EXPLICIT
LINES.
@THE EFFECT EXTENDS TO THE NEXT DIRECTIVE.
$B$I0
3.
$T1
$$@P NEVER CAUSES BLANK LINES TO BE INTRODUCED
AT THE TOP OF A PAGE; $$@B NEVER CAUSES BLANK LINES
AT THE TOP OF A PAGE EXCEPT IMMEDIATELY AFTER $$@N OR $$@V.

$T1
@SETTING .PAGE (PAGE SIZE) TO ZERO HAS THE EFFECT OF SUPPRESSING
PAGE-TURNS (AND CONSEQUENTIAL EFFECTS).

$T1
@VARIANTS OF THE ASSIGNMENT DIRECTIVE PERMIT PARAMETER VALUES TO BE
SELECTIVELY SAVED AND RESTORED (ON A PUSHDOWN BASIS; EACH PARAMETER
HAS ITS OWN NEST).

@SAVING (E.G.) : $T4

@THIS FACILITY OBSOLETES THE TEMPORARY VECTORS .TEMPA AND .TEMPB
WHICH HAVE BEEN REMOVED.

$T1
@THE SPECIFICATION OF THE VALUE TO BE ASSIGNED
IN AN ASSIGNEMENT (RIGHT-HAND-SIDE) MAY BE RELATIVE - UNDERSTOOD
TO MEAN RELATIVE TO THE EXISTING VALUE OF THE PARAMETER BEING ALTERED
(LEFT-HAND-SIDE).

E.G. $$@A .INDENT = +1; .TAB = -1,-1,-1,-1,-1

@SPACES ARE FREELY PERMITTED IN ASSIGNMENTS, BUT NOT IMMEDIATELY BEFORE
COMMAS OR SEMI-COLONS.

8.
$T1
@IF THE .ASCII PARAMETER IS NON-ZERO, UNDERLINING IN THE OUTPUT
DOCUMENT IS ACHIEVED BY MEANS OF @CARRIAGE @RETURN AND
OVERPRINTING. @IF THE PARAMETER
IS ZERO, UNDERLINING IS REPRESENTED BY 8TH BIT SET. (@ON .EMAS,
AND ANY OTHER SYSTEMS WHICH HAVE DIFFICULTY IN HANDLING BYTES
PROPERLY, THE EFFECT MAY BE TO IGNORE
UNDERLINING).

@NEW DIRECTIVE $$@J TO TERMINATE CURRENT LINE
WITH JUSTIFICATION (PROVIDED .JUST IS SET).
$B$I0
10.
$T1
@NEW PARAMETER .FINISH TO GO TOGETHER WITH .START TO LIMIT THE EXTENT
OF THE OUTPUT DOCUMENT. @NOTE THAT THE PROGRAM TERMINATES IMMEDIATELY
AFTER DEALING WITH THE PHYSICAL PAGE NUMBERED .FINISH
@AN UPDATED SOURCE SHOULD NOT NORMALLY BE GENERATED ON
A PARTIAL RUN, AS IT WILL BE INCOMPLETE.

@A QUESTION-MARK IS TREATED AS EQUIVALENT TO A PERIOD FOR DETERMINING
TH END OF SENTENCE.

$T1
@IF THE .MARK PARAMETER IS OTHER THAN ZERO OR 1, A @FORM @FEED
CHARACTER IS PRINTED AS THE MARKER. @THIS ALLOWS CORRECT ALIGMENT ON
