Question:

1. Is there an another way without using the package arrayjob?




2. How to get the random color for it?

Thanks.

 4.5 mul    between 0 and 4.5

 cvi        between 0 and 4

 } for.     end of for loop

Every square has a corresponding number 0 .. 53 which can be used
for color setting: 0 (red) 1 (green) ... and so on. see pages 38 ff of
the documentation.

The same for complete faces:
