There isn't a fixed limit. At one time the size= option had an associated list of acceptable values. The reason for this was to have the parser perform the check to ensure the value was odd, by specifying "1,3,5,7,..." as acceptable values. The limit was merely a consequence of the fact that such a list has to be finite. The list has long since been removed (the even/odd check is coded explicitly). I can't find any mention of the limit in the manual page; which version are you using? -- Glynn Clements <[email protected]> _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
