[GRASS5] Re: MASK in GRASS 5;.7

[Michael Barton]

This is a relief.

This is a simple procedure to name (or copy) any raster map to MASK. A 
couple of questions.

1. Is this the same kind of binary map as is used in GRASS 5.3? That 
is, operations take place in grid squares with a MASK value of 1, while 
those with a MASK value of 0 are ignored.

2. Does the name have to be in all caps (i.e., MASK vs. Mask or mask)?

Thanks for the info.
