You can specify a zero origin when you declare the array, for example:<BR /><P><BR />REAL MYARRAY(0:99)<BR /></P><P><BR />There is no "switch" to magically change the origin to zero.<BR /><BR />Steve</P> Thu, 04 Jan 2001 02:35:32 GMT https://community.intel.com/t5/Software-Archive/Array-Index/m-p/933798#M15406 Steven_L_Intel1 2001-01-04T02:35:32Z
