int startIndex = -1;
Log(s:"Collecting MAPINFO lumps.");
while(true)
{
startIndex = LumpOpen("MAPINFO", startIndex + 1);
if (startIndex == -1)
{
Log(s:"No more MAPINFO lumps found.");
break;
}
Log(s:"Next MAPINFO lump was found at index ", d:startIndex, s:".");
// At this point you can read its contents with either `LumpRead` or `LumpReadString`.
// Make sure to close the lump again to free the handle.
