fileread, lun, array, start, num,
Reads raw data from a file opened on logical unit
array (whose prior contents are discarded), starting at
start in the file (measured in units of a
data value) and reading
num data values. The data values
are assumed to be of the indicated
type (as from
#type), and the
array will be changed to that type.
start is negative, then data is read from the current
position in the file.
