* Draw strings are flexible with spacing. '''Spacing is not required.''' [[DRAW]] will look for a number value after a valid letter.
* DRAW statements are not case sensitive.
** "'''B'''" (blind) before a line move designates that the line move will be hidden. Use to offset from a "P" or [[PAINT]] border.
** "'''C''' n" designates the color attribute or [[_RGB]] [[STR$|string]] numerical color value to be used in the draw statement immediately after.
** "'''M''' x, y" can move to another coordinate area of the screen. When a + or - sign is used before a coordinate, it is a relative coordinate move similar to using the [[STEP]] graphics keyword. DRAW "M+=" + [[VARPTR$]](variable%)
** "'''N'''" before a line move designates that the graphic cursor will return to the starting position after the line is drawn.
** "'''P''' f [, b]" is used to [[PAINT|paint]] enclosed objects. f denotes the fill color and b the border color, if needed.
** "'''S''' n" changes the pixel move size of the lines. Default is 4 (1 pixel) minimum. "S8" would double the pixel line moves.
** "'''X'''" + [[VARPTR$]](value) can draw another substring.
''Example 1:'' Placing an octagon shape DRAW across the the screen using PSET.

''Explanation:'' Once a DRAW string variable is created, it can be used to draw a shape throughout the program at any time.
''Example 2:'' Creating an analog clock's hour markers using "TA=" + [[VARPTR$]](angle).
{{CodeStart}} '' ''
SCREEN 12
FOR angle = 0 TO 360 {{Cl|STEP}} 30 ' 360/12 hour circles = 30 degrees apart
PSET (175, 250), 6 ' stay at center point of clock
{{Cl|DRAW}} "TA=" + {{Cl|VARPTR$}}(angle) + "BU100" ' move invisibly to set next circle's center point
{{Cl|CIRCLE}} {{Cl|STEP}}(0, 0), 5, 12 ' circle placed at end of blind line
{{Cl|DRAW}} "P9, 12" ' paint inside of circle

''Explanation:'' To place 12 circles in a circle each move is 30 degrees. PSET sets the center of the circular path every loop. TA moves counter-clockwise with positive degree angles. Once TA sets the angle a blind Up move is at that angle. The hour circles use the end point of the blind line as centers using the STEP relative coordinates of 0. After the circles are drawn, a draw "P" string paints the circle centers. DRAW paint strings use the last coordinate position also.
''Explanation:'' The degrees to move from the original UP line move is calculated by dividing 360/60 seconds in a full rotation. That value of 6 is made negative to use TA correctly and multiplied by the [[VAL]]ue of seconds from the TIME$ function. The degree angle is converted by [[STR$]] to a string and added to the DRAW string using the [[STRING]] '''concatenation +''' operator. Do not use semicolons to create DRAW strings. Once the second hand is placed on the screen, a loop waits for the second value to change. It then erases the hand and it repeats the process again.
