eval(x [, n, /allnumber])
Compiles and evaluates a string, interpreting it as LUX code.
Non-strings are just evaluated. If
n and/or keyword
/allnumber are specified, then numbers are read from
n indicates how many numbers to read from
/allnumber indicates that all numbers are to
be read. The read numbers are returned in a scalar (if one number) or
array (if more than one number), and if no number is found then a zero
is returned for it.
