title: How to set missing values for all numeric variables
body: <p>I have a large dataset with both string and numeric data. The syntax <code>MISSING VALUES ALL (999).</code> did not work because SPSS requires numeric and string variables to be listed separately.<br />
  It will be a pain to use <code>MISSING VALUES var1 to varn (999)</code> command because variables are mixed.</p>
  <p>Is there a way to define missing values for all numeric variables at once?</p>
