Poly2_A & Poly2_b syntax bug?

Paul King — Sun, 17 Apr 2005 02:16:08 GMT

Can anyone explain why this works

poly2 4,7,
0,0,
10,0,
10,10,
0,10

but this gives "missing parameters" error?

poly2_b 4,7,1,1,
0,0,
10,0,
10,10,
0,10

Similar result with Poly2_A

Is this syntax incorrect or is there a mistake in the GDL manual?

PAUL,
I notice you are missing the masking values
in the POLY2_B command.
The POLY2 command does not require masking values.

I know you know this

Arrrgh!
Obviously quite right

Hate the way the manual is laid out - it assumes you read from front to back in sequence rather than skipping straight to the bit you wanted - you have to back up to the Poly2_ command to even find a definition for "status codes". And the link to "additional Status codes" does not actually list any - you have to back out of that & go back to main contents listing to find them.

Not ergonomically designed at all

Thanks for pointing out the obvious!!

PAUL,
Are you like me and many others that would like
GS to publish a hard copy of the GDL manual so
you don't have jump around inside a PDF ?
I wonder if you can stuff the ballot box in the wish list
