maths functions
STRIP will set the current strip colour in the window attached to the specitied or default
channel. The strip colour is the background colour which is used when OVER 1 IS
selected. Setting PAPER will automatically set the strip colour to the new PAPER colour
syntax: STRIP [channel,] colour
example: i. STR I P 7 [set a white stripj
ii. STRIP 0,4,2 [set a black and green stipple strip)
The effect of STRIP is rather like using a highlighting pen.
TAN will compute the tangent of the specified argument. The argument must be in the
range
-30000 to 30000 and must be specified in radians.
syntax: TAN (numeric_expression) [range -30000.30000)
example: i. TAN (3) [print tan 3J
ii. TAN(3.141592654/2) [print tan 7</2J
