─────$LOOPOPT───────────────────────────────────────────────────────────────
 
     Action
 
     $LOOPOPT turns on compiler loop optimization; $NOLOOPOPT disables
     it.
 
     Syntax  $[NO]LOOPOPT
 
     Remarks
 
     $LOOPOPT is the default.
 
     Loop optimization consists of placing invariant expressions outside
     the loop, and simplifying computations within the loop to speed up
     loop calculations.
 
     It is dangerous to turn loop optimization on and off locally.
     Loop optimization should be applied to, or removed from, entire
     programs or procedures.
 
     The $LOOPOPT metacommand is equivalent to the /Ol compiler option.
