title: set /A command expands with a comma for more than one var, only set does not
body: <pre><code>(set /a "m1=1,m2=2")
  for /f %%c in ("%m1%%m2%") do echo %%c
  pause
  </code></pre>
  
  <p>The brackets else where than due to the for command are used in cases, a space key should have been added.
  The echo of the for command, is 12. I used the number characters to face the set /A command with decimal Expression.
  When i try the same procedure only with a set for a Shell, may also be named m1 it is just possible without comma seperation.
  With set command the m1 Expression would be 1 m2 2 and not two values like with a set /A SET.
  Is there a way to use set only once and not only with the set /A?</p>
