 LOAD. Programs stored in blocks frequently have "loader blocks"
 that take care of loading all blocks relevant to the program.
 
+Blocks spanning multipls disks are tricky. If your media isn't
+large enough to hold all Collapse OS blocks in one unit, you'll
+have to make it span multiple disks. Block reference in
+informational texts aren't a problem: When you swap your disk,
+you mentally adjust the block number you fetch.         (cont.)

+However, absolute LOAD operations in Collapse OS aren't aware
+of disk spanning and will not work properly in your spanned

+Although the usage of absolute LOAD calls are minimally used
+(relative LOADs are preferred), they are sometimes unavoidable.
+When you span Collapse OS over multiple disks, don't forget to
+adjust those absolute LOADs.
