The problem is not the number of array elements but the number of statements within a function. If a javascript function in IE7contains more than 32768 statements it generates this 'syntax error'. Now a javascript function contains rarely more than 250 statements unless you are filling a big array with assigment statements of course . A workaround for this is using multiple functions. Also it seems if you make multiple blocks (using { } ) within a function where each block contains less than 32768 statements the error also disappears. So the real cause of the problem in IE7 seems to be that they are using a short integer to count the number of statements within a block.
We recommend that you use standards-compliant XHTML on pages that contain maps. When browsers see the XHTML DOCTYPE at the top of the page, they render the page in "standards compliance mode," which makes layout and behaviors much more predictable across browsers. If you want to show polylines on your map (like the lines used by Google Maps to show driving directions), you need to include the VML namespace and some CSS code in your XHTML document to make everything work properly in IE.
