5.3. CONST_DETECT

Format:

        PRAGMA OPT CONST_DETECT { YES | NO | }
      

YES -- enable constant detection

* NO -- disable constant detection

Look for variables that are defined but are either only assigned once, or are always assigned the same value. When this happens, replace all occurances of the variable with the constant.

nb : PRAGMA CLEAR will prevent this option from having any effect unless the variable is only assigned the constant 0.
