What were you expecting to "happen"? If these are the only commands
that you asked to be carried out, there would be no visible "happening",
because no output has been called for. There will have been a variable
named "zread" created by the COMPUTE/EXECUTE sequence and stored in the
active data file, but if you have not asked for output you won't get any.
You might have asked, for example, for the mean(s) and standard
deviation(s) of this new variable (and perhaps other extant variables);
or for a correlation matrix among several variables, including this
variable; or for a listing of the values of this variable (if the
number of cases is not prohibitively large).

Yes, that sounds reasonable, since any alteration would probably result
in misspelling one or more command name(s) or variable name(s).
