JOIN. This joins the current cursor position to the LSP
last saved point) with a white ‘line’. By ‘line’ I mean
the shortest distance between the two points using the
block pixel graphics. This usually resembles a
‘staircase’ ! The LSP is reset to the current cursor
position. ‘Line’ drawing becomes quick and easy!
MOVE. The cursor may be positioned anywhere on the NASPIC
page by use of the normal cursor control keys. The cursor
is blinking and non-destructive. There is no wrap around.
The NASPIC page is from line 1 to line 14 inclusive.
OPTIONS. This command sets the rates for cursor speed
and repeat. The cursor speed may be from <1> (fast) (and
it is), to <9> (slow). The repeat is enabled by <Y;gt> or
disabled by <N;gt;. For the repeat with NAS SYS 1 you need
the Bits and PCs Toolkit.
PROGRAM. This compiles the current NASPIC page to a BASIC
program and appends it to the end of any existing BASIC
program (it doesn’t matter if there lsn’t one). As in
<CS> there is a <Y/N> prompt before the procedure is
carried out. When ‘compilation’ is completed the user is
returned to BASIC. N.B. BASIC must have been cold started
before NASPIC can used to produce the final product.
QUIT. This clears the screen and returns the user to
NAS-SYS. It’s a bit of pity you don’t have the option
to chose between NAS SYS and BASIC.
RUBOUT. This is the opposite of draw i.e. it leaves a
black ‘line’ behind it. However, any character cell not
containing pixel characters is blanked out. This means
you can’t draw black (and for that matter white) ‘lines”
through your graphics and text characters.
SAVE POINT. The current cursor position is set as the
ISP and is of course for use with the JOIN and UNJOIN
TEXT MODE. The keyboard is now enabled and text can be
entered on the screen. The repeat key is disabled to
prevent keyboard ‘bounce’. The left and right cursors
provide wraparound on the same line. The entire
graphics set is again available to the user but of course
to enter a graphics character you need to know the right
combinations of keys to get them. Hence the the rather
clever idea of the CHARACTER mode.
UNJOIN. This is the opposite of join i.e. it draws a
black ‘line’ from the current cursor position to the
