Empty a list of globals

[Mark MacKenzie]

Hit a bit of a stumper for me.

At preopencard time I need to clear a bunch of globals.  I created the 
following handler and it doesn't seem to clear the globals involved.  In 
a succeeding handler they keep their previous values.  Am I doing 
something fundamentally wrong?

preOpenCard
put 
"gBulletCalibre,gBulletDesign,gBulletSizedDiam,gBulletNomWeight,gBulletLotCustom" 
into gGlobalsToEmpty
    repeat with x = 1 to the number of items of gGlobalsToEmpty
      put empty into item x of gGlobalsToEmpty
    end repeat
end preOpenCard

When faced with a series of globals to reset to zero or empty how do you 
do it with a minimum of scripting?
