[Coco] Obscure DRAW feature from ECB Unravelled

[tim lindner]

I found this in the unravelled book:

******************

There is a certain syntax that must be followed, which to my knowledge
has not yet been published anywhere until now. Following is a short
example of how to do this.

  10 A=10:B=13 
  20 DRAW "BM=A;,A;;U=B;R=B;D=B;L=B"

The above program will draw a box that has sides equal to the variable
'B', as the program stands, line 20 is equivalent to the following: 

  20 DRAW "BM10,10;U13R13D13L13"

*************************

But there are two typos in the DRAW command. It should look like this:

  20 DRAW "BM=A;,=A;U=B;R=B;D=B;L=B;"

The vairable name has to begin with and equal and end with a semicolon.

Neat.
