#X text 160 621 - the float read from the array at the specified index
\, with cubic interpolation if applicable., f 68;
#X text 160 378 - an incoming float indicates the index at which to
read. For non-int indices \, the cubic interpolator uses two points
on either side of the indicated index to calculate a value. This limits
valid index values to ranges from 1 to 2 less than array size (i.e.
n-2) in positive numbers \, and from -2 to -n+1 in negative numbers.
Indices 0 and n-1 are guard points \, and are not directly readable.
Negative indices are added to the array size \, so that index -1 points
to the last element \, -2 to the penultimate \, and -n to the zeroth.
An onset greater than n-2 or less than -n+1 refer to the last and first
readable indices \, respectively., f 68;
