I need a small routine that would allow the 'image' operator to read
runlength encoded 8 bit images.  That is, each hex grayscale value is
preceded by a value that indicates its repeat count.  For example,

    ff01

means 256 (repeat count +1) values of 1.  This is useful to reduce the
amount of data that must be sent over the communication line.  

Please respond via Email to cristy@dupont.com.  Thanks muchly in advance.
