	~~One of the specialized routines in the~~ Color 64 ~~ML is a "fast~~ garbage collection~~" feature~~. Garbage collection is the ~~term used to describe what the computer does when it cleans~~ memory ~~of garbage strings~~ that ~~BASIC~~ is no longer ~~using~~. In standard ~~C64~~ BASIC ~~the delay during garbage collection~~ can ~~be quite~~ long~~, which decreases~~ the ~~performance~~ of ~~programs. The Color 64 fast routine decreases the amount of time that this collection takes~~.		Color 64 includes an enhanced machine language routine designed to speed up garbage collection. Garbage collection is the process by which BASIC reclaims memory occupied by string data that is no longer in use. On a standard Commodore 64 running BASIC alone, this process can introduce noticeable delays, sometimes long enough to interrupt the flow of a program.

	~~Some of the~~ Color 64 ~~BASIC routines~~ that ~~specifically take advantage~~ of ~~this feature are the regenerate message index and the directory regenerate routines. You will notice that the screen goes blank sometimes~~ while ~~these routines are working. This is because a blank screen will allow the computer to work faster. Also~~, ~~SYSOPs with Commodore 128 computers will have a bonus:~~ the ~~garbage collection~~ routine ~~will work at 2 megahertz~~.		The Color 64 fast garbage collection routine significantly reduces that delay. Instead of waiting while BASIC slowly reorganizes memory, the ML routine streamlines the cleanup process, resulting in faster overall system performance.

	~~Note that on a stock~~ Color 64 ~~system the fast routine is not always active. If you want to have the routine~~ on ~~all the time, allowing faster operation of the BBS system~~, ~~then you should edit line 10241 of √bbs.init and change the part that says "M7=." to read "M7=1".~~ ~~You will notice the screen blanking more often, but this just shows that the fast routine is active.~~		Several Color 64 BASIC routines rely heavily on this optimization, including:
			* Regenerate Message Index
			* Directory Regenerate

	For ~~more information on this feature~~, ~~see~~ the descriptions of the !48 and !53 variables in [[ml variables\|ML Variables]] ~~Section~~.		During these operations, you may notice the screen going blank. This is intentional. Disabling screen output allows the computer to complete memory operations more quickly. The temporary blank display is simply an indicator that the fast routine is actively working behind the scenes.

			SYSOPs using a Commodore 128 gain an additional advantage. When running in 2 MHz mode, the garbage collection routine executes at double speed, further improving performance during intensive operations.

			By default, the fast garbage collection routine is not always enabled. If you prefer to keep it active at all times for maximum system responsiveness, edit line 10241 of √bbs.init. Change:
			M7=. to: M7=1

			With the routine permanently enabled, you will observe more frequent screen blanking during memory-intensive tasks. This behavior is normal and confirms that the accelerated garbage collection is in use.

			For additional technical details, refer to the descriptions of the !48 and !53 variables in [[ml variables\|ML Variables]].

<strong>Fast Garbage Collect Routine </strong>

One of the specialized routines in the Color 64 ML is a "fast garbage collection" feature. Garbage collection is the term used to describe what the computer does when it cleans memory of garbage strings that BASIC is no longer using. In standard C64 BASIC the delay during garbage collection can be quite long, which decreases the performance of programs. The Color 64 fast routine decreases the amount of time that this collection takes.

Some of the Color 64 BASIC routines that specifically take advantage of this feature are the regenerate message index and the directory regenerate routines. You will notice that the screen goes blank sometimes while these routines are working. This is because a blank screen will allow the computer to work faster. Also, SYSOPs with Commodore 128 computers will have a bonus: the garbage collection routine will work at 2 megahertz.

Note that on a stock Color 64 system the fast routine is not always active. If you want to have the routine on all the time, allowing faster operation of the BBS system, then you should edit line 10241 of √bbs.init and change the part that says "M7=." to read "M7=1". You will notice the screen blanking more often, but this just shows that the fast routine is active.

For more information on this feature, see the descriptions of the !48 and !53 variables in Programming Section.
