Functions RLB, SLB, SRB, RRB, contained in the BIT menu, are used to
manipulate bits in a binary integer. The definition of these functions are
shown below:
RLB: Rotate Left one byte, e.g., #1100b #1001b
SLB: Shift Left one byte, e.g., #1101b #11010b
SRB: Shift Right one byte, e.g., #11011b #1101b
RRB: Rotate Right one byte, e.g., #1101b #1110b
Hexadecimal numbers for pixel references
Many plot option specifications use pixel references as input, e.g., { #332h
#A23h } #Ah 0. 360. ARC, to draw an arc of a circle. We use functions
C PX and PX C to convert quickly between user-unit coordinates and pixel
references. These functions can be found through the command catalog
(
‚N).
Some examples are shown below:
