It takes the results of an unstored calculation and pushes them out to the disk. Normally they just sit in the CPU's cache until they're needed for display purposes. Sometimes, however, this means that OLD results continue to be displayed on your screen, when what you WANT to see are the NEW results, from the most recent calculation. Before this command became available, the standard work-around trick was to go to another page, then return to the one you were looking at, at which time FMP would update it. This was a nuisance, thus the arrival of this "make it appear now" option. Generally this does not add to file size, since you're going to add those calculation results to the file at some point anyway. It CAN, however, slow you down while the results are being transferred from the CPU to the disk. Unless you're dealing with truly massive amounts of data, any such slowdown is probably measured in milliseconds. The take-home point is that this command lets you see accurate results on your screen the instant that the calculation is concluded; I figure this is worth a lot.
