I will put in a plug for Jacques Paris' books "MiniGuide to the MapBasic
Window" and " My (MI) Bag o'Tricks". They seem to capture everything
useful the manual left out.

Greg's summary helps me immensely, owing to my limited programming skills
and vast ignorance. Namely,
To capture the colour of polygons create a new 40 Character field in the
table and use Update Column with the following value
objectinfo(obj, 2)
This will return for example
Pen (2, 2, 16711680) (which is red)
Pen (2, 2, 65280) (which is green)
Pen (2, 2, 255) (which is blue
I experimented a bit and determined that 2 is the integer attibute value
for pen, 3 for brush. Is there some way to find the list of all integer
attribute values needed for objectinfo's argument 2? I tried the RTFM
method first, to avoid wasting list time. But I come up empty handed.
Sincerely,
David
