EW
FUNCTION: ECAM Widen Segment
DESCRIPTION:
The EW command allows widening the length of one or two ECAM segments beyond the
width specified by EP. For ECAM tables with one or two long linear sections, this
allows placing more points in the curved sections of the table.
There are only two widened segments, and if used they are common for all ECAM axes.
Remember that the widened segment lengths must be taken into account when
determining the modulus (EM) for the master. The segments chosen should not be the
first or last segments, or consecutive segments.
ARGUMENTS: EW m1=n1,m2=n2
where
m1 is the index of the first widened segment. m1 is a positive integer between 1 and 255.
n1 is the length of the first widened segment in master counts. n1 is an integer between 1 and
2,147,483,647.
m2 is the index of the second widened segment. m2 is a positive integer between 3 and 255.
n2 is the length of the second widened segment in master counts. n2 is an integer between 1
and 2,147,483,647.
If m1 or m2 is set to -1, there is no widened segment. The segment number m2 must be
greater than m1, and m2 may not be used unless m1 is used.
