Function: GDSC_FILL
Purpose: return coordinate word filled with a grid value for each axis.
Category: GDS
File: gdsc_fill.c
Author: W. Zwitser
Use: INTEGER GDSC_FILL( SET, Input character
SUBSET, Input integer
GRIDS ) Input integer
GDSC_FILL coordinate word filled up; -1 in case of error.
SET set name
SUBSET coordinate word to be filled.
For each undefined axis a grid value is added
from array GRIDS.
GRIDS array with grid values.
This array should contain as many elements as
the number of undefined values in level.
Description:
This function is very useful inside a loop over all subsets to
compose the coordinate words of the next subset.
The subset level is available from GDSINP and the box corners
(in grids) are returned by BOXINP. Adding the minimum grids to
the subset level gives the lower left coordinate word and adding
the maximum grids to it gives the upper right coordinate word of
the next box.
